Lost about him

I don't know if I have feelings for this boy he makes me feel happy and makes my smile he knows me like the back of his palm I seriously know everything about him top to bottom everything what he goes through what he feels but lately he's been acting a bit of a jerk we were each other's first for everything except sex we till have our v cards sometimes we seem perfect for each other then other times we aren't I don't know anymore everytime we push each other away we become closer then before but it's seems that I'm losing myself and I'm lost I have depression he knows that he can make a bad day a good day for me but we seem with one step forward 2 steps back we know each other for 6 months or less I seriously care for him but I feel like we can do anything together but then there times when we can't and that's start to occur more and more he just I don't know anymore And I can't tell him how I feel cause he won't date me till I'm 16 atm I'm 15 and he won't date me cause he turn 17 about to turn 18 we both know we have feelings for each other but he refuses to accept them  cause he says he'll hurt me (emotional) he's done it twice already
