Welcome to the board.
It sounds like the relationship has been in trouble for awhile.And from what I have read it is a two way street. Neither of you are at total fault. And quite frankly sometimes people just grow apart. It is as simple as that.
I am not an expert in relationships by any means. But,I do know that if you keep going like this then you will just grow farther apart and neither of you will be happy.
I guess you need to ask yourself one simple question:
Am I better off with him or without him
List the pros and cons for both sides and go from there.
You both deserve to be happy and fighting and breaking up and getting back together is only going to cause alot of emotional stress and I don't think that is something that you want to do.
