It sounds like he’s broken up with you and you’re unhappy about that. Unfortunately, you can’t make him do something he doesn’t want to do, and while you may think you were happy, he doesn’t share your view. At this point, since he’s already established a break in the relationship, the best advice I can give you is to be your best self. If he misses you enough to want to see you, at that point he’ll see you being the best you can be, and at that point he’ll be able to ask you out again and possibly re-establish your relationship. BUT….if he’s done for good, the best you can do is understand that the fighting is what caused the break, and when you look for Mr. Right and get out there and start dating again, try and find someone who is more compatible with you and with whom you don’t have as many fights.
I’m sorry you’re hurt. Put your energy onto you, and not him, and live your life the best way you can.
