Would you forgive me? I don't know what to do.?

OK this is not easy. You cannot control your friends emotions. You can only manage your own behavior. If he will not forgive you then you need very badly to drop it and move on. I have no idea what transpired so it is hard to say what anyone would forgive or not forgive. But it somewhat doesn't matter. What matters is that he is not willing to try to move on with your relationship. So at this point it will not be easy but the correct thing for you to do is to drop it and work on moving forward in a different direction. In time maybe he will change his mind but you cannot force that issue. So look for healthy ways to find new Friends and work to build new relationships. That is what you need to be doing now. Best of luck.
