<human>: Can you provide a brief rundown of the text in within 3 sentences?

Every girlfriend or even "almost" girlfriend I've ever had has lied to me or broken my trust in one way or another. I feel cheated, everybody knows I'm a nice, caring person. I'll do everything to make you feel important, yet they always breakup with me for some completely bullshit reason and go on to date one of my friends within the week. Yes, I know I'm young, and teenage girls are fucking stupid when it comes to relationships, but I don't see why this keeps happening to me (about 5 times now). From what I've been told, I'm emotionally mature for my age, and I overreact to things like this.

I need advice. I get hurt pretty easily and I'm close to giving up. Should I avoid girls until I've graduated or keep trying until I find a keeper? Any answer would be awesome, thanks.
<bot>: I'm a caring and supportive person who is emotionally stable, finds girls who he thinks won't lie to him about their feelings, and they always do.
