I am seriously like... in love with this girl.?

I don't think you are going to find that many grade 9's that are concrete Lesbians and know it yet, let alone were suspicious all the way back to grade 7. This question gets asked a lot, and although she doesn't want to have a relationship behind her mom's back, if she really cared for you she would try and make it work. Whenever you would go over to her house, just pretend like you guys are just friends, and everywhere else be Lesbians. If she isn't willing to do that, is she really worth it?
