None of us can tell you what to do or when to do it. It looks like you have really good reasons for doing what you are doing. Protecting your sister and a girlfriend are important things.  When you are trying to protect people, yourself included don't consider it lying. If a person asks you a question in order to gin a weapon to use on you there is not duty to answer and arm that person.
Let's look at what we do know from this. You are out where it is safe for you to be out and where it is safe for others who are close to you. You are not out where it can be dangerous. Cool but you are out somewhere and that is not even the start of the process, that started when you came out to yourself. And you are out to the girls that you love, so that is great.
We also know that you will be completely out someday, somewhere and in your own time. That is best done, in your situation, when you are not subject to others in school administrators and parents. Some other people can be out with supportive parents and teachers, but that just isn't an option for you.
Coming out is a process that you have started and that you are engaged in. It is a process that moves along in steps. Even as old as my fat butt is I still have to do it sometimes, I have to come out because someone assumes something. But you are doing it right now, you are coming out. You are taking it exactly the way you should step by step according to what is best for you and the people whom you love. Not at my speed or the speed that anyone else says is right but at the speed that works for you.
You are not in the closet, you are coming out and you are doing the right way for you in order to stay safe and make progress.
Looks like you are right on time keeping yourself safe and opening up when and where it is safe.

Thankyou, Maestro. That actually makes perfect sense^^
I've talked it through with Rhiannon, and she wants me to move in with her when she turns sixteen and is emancipated. So, then if everything works out like it should, and we're living together, and don't have to worry about parentals severing ties, or us hiding, then we can come out to everyone together. So, her  way seems logical, and I'll go with that. Susan *my sister* will have graduated by then, and if not, she'll be in her senior year. After Rhiannon and I graduate, we're going off to a state with at least domestic partnership rights. Prefferably Oregon, because that's where I intend on going to College. Rhiannon says I saved her life, and she could at least repay me by protecting me. *I actually had no idea. She said that before she met me, all her smiles were fake, but I was the first person she has ever been happy with . Sweet isn't is?^^* So it should all work out.

 Good, I'm glad that you guys have a plan.

Me too :D
It seems you're the only one that ever replies to any of my forum posts XD Thanks for that^^

I miss outminds. Too bad it went down in flames. 

I never experienced the epic-ness of Outminds.Only OpenMynds.
What I did experience was probably the worst day I've had this year. Rhiannon's uncle found out about us. *Rhiannon lives with her aunt and uncle. They are her "parental units" as we call them* He searched her computer, and read all of our emails and found EVERYTHING, and thus he flipped the f*** out. After hours of screaming at her, he told her to stay away from me, and to break up with me, and also put an end to any social life she had. Heh said if he found out we're together still, they'd take her out of school. She told me today, but she said she would NOT break up with me. But we can't hang out at school, and we can't sit together at lunch or hold hands. All we have left is our notebook. **we have no classes together, so we  have a notebook instead, so we pass the notebook back and forth between classes**.
So... today I cried until my eyes were utterly dry.  As did she. She hadn't cried in years. She thought she was physically incapable of crying, and she hated it... but I never want to see her cry again. It just made it worse with each person who asked "hey, what's wrong?" I only told a few people; the ones we both trust. The only part of my day that made me feel even slightly better, was when as I was walking to my last class of the day, on the verge of tears, Christen stopped me, and hugged me, then Addison *he's Rhiannon's best friend, and he's one of my closer friends* joined in, then so did Dakota, and Matt *who's actually Rhiannon's ex boyfriend, so that was surprising. I figured he'd resent me.* and Billy, and Nick, and someone was hugging me from behind, so I was actually pretty confused. But those are the people that actually care. Then the moment was ruined because right as I walked into my sixth period, Mrs. Coffey *she stands at the door* stopped me and wanted to know what was wrong, and was like "You want to share it with the class..? Maybe just write it down?" Ugghhhhh.... I just kept shaking my head, then went and sat down. 
 lunch, forrth, and after sixth period were the worst. At lunch, I found out that Rhiannon couldn't even sit with me anymore. After lunch, I was walking with her as always, but I could tell I shouldn't have, so I took the other route, but I still stood outside the art room, because I wanted to ask her if we could still talk. But I waled up to her right as the doors to the art room were opening nd she just left. :( Watching her just walk away was terrible, and it was even worse that she was crying. Same as after sixth period, walking to the bus. I saw her and Addison walking to the bus. Usually I meet her afterschool, but she was just leaving. I guess i's for the best, though. We have a chance, with the notebook. Her uncle deleted her myspace, and read her emails, so I can't talk to her online either. At least we have the notemook..
:/

 Wow, bad news. I sorry that you guys are having things so tough. Her uncle sounds like a real winner. Keep putting everything in the notebook. Nothing is forever and at some point you will be in charge of your own life as will she. Keep looking forward and keep moving forward.

Thanks again, Maestro. It's like you always know what to say.
All I know now, is that things are going to be really hard......

 wow, sounds almost like my first gf and i, except we didn't go to school together. my mom caught us and i got hell for it, i wasn't allowed to communicate with my girl at all, needless to say she had a mental breakdown. but my mom finally saw how seriously i am about my life and she cooled off and chilled out about the whole gay thing. depending upon how her parentals are, anything could happen. so i just looked at your profile, are you really only 13? if so, you really need to do some thinking about your life, you're REALLY young, and a lot of stuff is going to happen in the next couple years that you can't even wrap your head around right now. don't count all your ducks right now, cuz i don't mean to be the bearer of bad news, but there's going to be a lot of heartbreak to come, so it's best to prepare for it now.

Yeah there is. I know things are going to continue getting harder, and it's going to be unbearable to go back to school monday and see her the same she was yesterday, and we both know a lot of bad shyt will happen :/ My heart's been broken before, and it will be broken again, I know. I may be young, but in my lifetime so far, I've gone through a lot of shyt. Mental/physical abuse from the time I was a toddler to when I was about five, thinking about girls when I was so young I ididn't even know what sexuality was, which resulted in my grandmother flipping out and telling me that homosexuality is a sin and we'll burn an eternity in Hell for it, then my dad being too f***ed up on drugs to take care of my siblings and I so w had to stay somewhere else, *few years later* my best and only friend nine years running telling me she hates gay people, then proceeding to start rumors and hate me, meeting Bekah, and afterwards having her destroy me, then meeting Rhiannon who wanted to help me, and eventually asked me to be her girlfriend, knowing the consequences, then being destroyed by those around us...... :/ But yeah. I'm a 7th grader put in the same school with 8th,9th,10th,11th, and 12th graders. What kind of genious thought of that? :/

 who knows, some people are just a bit sadistic when it comes to things like that. but hey, just be strong, early adulthood is exponentially better than life in public school.

 All those graders together? Too bad. When I was in elementary in a little farming town everyone went to the same school complex all ages and grades but most places have them in different schools now. Take care.

Yeah man. Two elementary schools, then a 7th through 12th junior/senior high. I curse the genious who thought of that.-_-'
...So I talked to my mum about all of this shyt. Considering it can't really get worse with the parental thing, and my mum already knew I was a lesbian, and it's obvious there's something wrong, I just told her. She (thank the Goddess>.>) didn't flip out, but apologized.... but she made me tell the male parental unit. >-<' But since I was all emoey and stuff, she went and bought me coffee, jelly beans, a 288 page Hello Kitty coloring book, and pizza xD Little kid things tend to ease my emoeyness, I've discovered. So I made Hello Kitty rainbow, and ate too many jelly beans. XD
 I don't want to go back to school though. Not like this. I jsut want it all to go back to normal... this is worse than the bullying and the name calling. This morning I woke up, and thought it was all a dream. Then I remembered it wasn't, and it felt like it was all happening again. Same thing when I woke up yesterday, after crying myself to sleep. I thought it was all a dream.
 I wrote a new song. I tend to do that when I have something on my mind. Most of them turn out to be FAILs though. So I just forget about them.

yeah, it's going to hurt like hell for a while, but things do get better. you just have to look forward to better things.  

 You should start keeping the songs. I'm glad that you parents didn't freak at you and showed you some support. That is important.

I still have all of them. I put them in the back of the binder thingy I use. I just don't play them. I found a melody for the one I just wrote. I used my FAIL Scale, which seemed to fit perfecly with it. **I call it the "FAIL Scale" because I was epically FAILing at a song I just wrote, so I stoped and repeated "FAIL" over and over again in a pattern. xD thus creating the FAIL Scale.**
but yeah...
The last song I wrote also describes the situation. I wrote it as more of a premonition, back before anything bad started happening at school, or eople trying to get between us. Near the end, there's a few lines like "Another day, my lovlie, I know that it hurts, just be strong, my lovlie, we'll make this work." <---- Strange how that describes what just happened. I wrote the song over a month ago.

 Songs tap into some very deep levels of personal stuff.

Yeah, they do. So do poems, but I don't write those as often as I used to. Unfortunately, I don't have all of my poems anymore. I was having an emotional breakdown a couple months back and tore them all into little pieces and threw them away... Terrible mistake on my end. I have no idea why I did it. A few of them were actually worthy, but a lot of them sucked. >-<'

 To be pragmatic here. I have to say that I am really glad that you understand how hard this is going to be. It is a hard set of events for anyone and being one of us can make it harder. I'm also glad that you recognize that you can get through it and that there is another side in the distance. Keep taking care of yourself. So start a new poetry collection, and put copies of them somewhere where you won't destroy them in a moment of pique. I usually make sure that I have electronic copies of my songs and poems.

Yeah, I've been doing that lately. I have several copies of the last few songs and poems I've written. Considering the majority of them I wrote for Rhiannon, they're in our notebook, as well as my binder thingy, and a third copy under my keyboard stand where I write most of my lyrics. :D
 I'm currently in the process of writing another song. I'll finish it tonight, most likely, since I'm working on it as an assaignment in school.  On the subject of creativity, I'm startng to do portraits of people! :D **said portraits started out by me drawing zombies, and I'm starting to draw my friends as well.** I stopped drawing for a whle, mainly only doing random little doodles on the side of my class assaignments, then started drawing again, but then I ran out of paper. xD ...but I have paper now! :D
 Yeah, anyway....
The thing with Rhiannon is working out. I told her to meet me in the girls' bathrooms on Fridays during lunch, you know, just to catch up and stuff. I always take the notebook home now, so there's no chance of her uncle finding it. *he went through her backpack as well, after he went through her computer. The dude has major issues-_-' * And basically,. this whole thing is like Romeo and Juliet (or rather "Juliet and Juliet") Kenny told me the same thing. Just hopefully we won't die at the end... well, we all die, but you know what I mean>.>'

Keep your head about you and keep looking forward. 

Haha, you're so philosophical, :D
I can be like that too.... even talking about Zombie Apocalypse >.>'
I finished my poem/lyrics. :D It's more of a poem, though, so I'll just keep it at that. It's really long>.>

 Hey, my degree is a philosophy degree, a really specialized and useless one but it was fun to get.

How would you get one anyway? :)
What would you even use it for? xD

 There are a lot of schools with philosophy degrees. Try one for martial arts philosophy concentrating in religious thought. Then a seminary type program. Messed up, fun and useless.

Haha, okay then. :D
You know what else is fun and useless? :D ....because I don't.-_-'
...so today some douchebag stuck gum in my hair... I hope he or she gets lice.-_- KARMA. ....!!
.....Oh well. I cut it out. xD People are douchebgs though. >-<'

 Next time use peanut butter to remove the gum. Work it into the hair above the gum and just keep working it out. OMG I have too many kids, why do I have to know this stuff?

Haha,. someone told me that. I was like ">.>'....... My hair is long and wavy. You won't be able to tell.... just cut it out.... please." I used ice....... xD
Muh lovlie girlfriend got most of it out when it happened. xD ....but then it just kind of spread out.
'Sides, you can't tell I cut it out. :3
Like I said, my hair is long and wavy. :3
