What should I do to get him back and prove I love him?

I am not saying this to be mean but who is the looser her your boyfriend or you?
Is he really worth holding on to or does he really have another women in bed already?
If this is true there is nothing you can do to get him back and I don't think he is worth it.
My best advise is to move on either way I think you are worth a lot more than he is if he wants to break up, maybe next relationship go a bit slower and get to know your boyfriend more first make sure he is real not just surface.

You should do nothing, this is the only way to get a guy back, most of guys are pushed away the more you fight for them and trying to get them back.

If you really love him and he wants to break up and you still love him let him see how dumb he is to have left you

Some of these answers are mean...but true. I know EXACTLY how you feel. That is the absolute worst feeling in the world- to want to stay together, while the other person doesn't at all. I am so sorry, but the truth is there is nothing you can do to "prove" your love to get him back. He's not necessarily a jerk, but maybe he doesn't feel the connection you do. How long have you been together? If its less than a year, it sounds like this might not be meant to be. If its been longer than a year, I would suggest going through with the break up, or taking a break. My boyfriend recently got so mad at me that he ended our 2 year relationship just like that. I suggested we take a 2 week break and see how we felt afterwards- and he agreed. I was crushed. I didn't eat, sleep, or even go to work. 5 days later he calls and says he can't do this anymore and wants to stay together. Giving him some space may make him change his mind, or at least decide to give your relationship another chance. But seriously...i tried to "prove" my love too and it didn't work. Guys have to love you on their own. A great song you can listen too is Usher- Throwback. I kept playing it over and over and looks like it's true!

Why be with someone who doesn't love you! Get over it!

Girl, you don't have to prove a thing. Does he have a good reason to break up with you in the first place? If he really loves you, he'll see what mistake he's making, if he doesn't... well it wasn't meant to be, and realize that there's TONS of guys out there and he's not worth all of this.

You shouldn't have to prove anything to a man who can't / doesn't / won't love you back equally. You will find someone MUCH better. Don't even waste your time on him!

First of all you should let him be aware of how you feel but do not act desperate. Then get on with your life. If he is going to come back then he will see you doing well and remember what you had. This is the only way although it is tough. Desperate is unattractive to all genders.

If you wanna really want to get back with him then tell him how you really feel or just try to make him jelous. But if that doesn't work and you wanna get rid of him then just start lookin for somebody new.

Sometimes I go shopping and I see a cute top. Immediately I decide I MUST try it on. Well we all have unique bodies and all of a sudden the top looks like a total mess. But then I see something else and I try that on and it compliments me. My point? Thing don't always fit, but be patient and keep looking around and soon youll find a perfect match, a guy that you don't have to fight for and waste precious time arguing with. Youll find a guy that fits, and that complimetns you!

Has he told you WHY? that would be the first info we need to help you.
