WORST LOVE LIFE EVER??!!!?

I'm 13 and last year in 7th grade there was this guy "James" and we totally hit it off but instead of dating me. He dares another girl(like always) who is also my friend. So in the summer she moved and all I could think about is him. Earlier this year he's being a total jerk to me!!WTF?! Tell all his "homies" I was obsessed with him and ****!! He's got nerve right?! He's calling me names and shizz!! So anyway, in september there was this other guy "Isaiah" and we also hit it off for 6 months then in Jan. he asks me out and I said yes and right after he says nevermind!! WTF?! He also dates one of my friends. Isaiah and I got in a huge fight in class cuz he called me something rude..but now..after all they said I still have feelings for them..not James he a db...just Isaiah..what should I do?
