Should I fight to get him back?

He chose his friends over you. Perhaps his relationship with them is stronger, thus more valuable to keep. It sounds like he isn't ready to break away from his group, which means that he's not ready for a relationship.

Why do they have more power than you? Is there something your doing wrong? Are these new friends? Or the same friends he's had since you two got together? Why does his friends hate you? Nobody breaks up with a girl "just cause of his friends" there has to be more to the story. If you don't want to lose him, ask him what you're doing or not doing to make him break up with you. Thats all you can do. Don't fight, you shouldn't have to "fight" to get him back. You should make him want to come back.

Listen see well if he really loved you he stand up for you also bros before hoes is gay love is more powerful than that so tell him its fine its your loss okay I bet your so nice loving and well pretty that hell notice his gay mistake

If a guy breaks up with you because of his friends it sounds like he needs to grow up in the first place. This doesn't sound like someone you should want to be with no matter how long the relationship lasted. Even if you and his friends don't get along personally I think he should still be able to have fun with his friends and still be a good lover to you. If he can't distinguish between the two, no you should not fight for him. He should be a peacemaker if he loves both sides, when he took sides that would have shown me a lot.

Do you really want a guy who, either, doesn't want to be with you, OR isn't with you because of his friends? He's not ready, or willing to commit. You want a guy who WANTS you. Letting him just go, and trying to move on, would probably be a healthy bet right now. Keep in mind, if he doesn't see himself as a doormat to the people he hangs out with, if this is really how it is, you probably want to rethink if he's a good match for you...if he gets walked on now, that's not likely to change anytime soon...if he's not a stand-up-guy for himself, you gotta believe he's also not likely to be one for you. You're young, take a breather a minute, do some research on the internet regarding healthy and unhealthy relationships...sit back and analyze this a little...I don't mean to be critical of him, but the picture you paint of him, from what I know now in my life? (I'm 44) I can only reference the 'ole adage, "if I only knew then, what I know now..." I'm not so sure he's worth fighting for. If you decide to, be certain what you are really fighting for...him? a bruised ego? attention? to avoid being lonely? Just be sure. Maybe this happened for a reason...maybe there is a really great guy out there that is meant to be with you, more deserving of the "fight" in you? Who knows really, but try to figure some of this out before acting on it, for your sake. Good LucK!!!

If you let him go, you do take a chance of losing him. But, do you want a guy who can't stay by you and will let his friends tell him who to be with? You sound like a strong girl. Go off have some fun. Find someone who deserves you and will fight for you not vice versa.
