Most Helpful Guy
He clearly has no idea what he wants. There's no reason for you to be fighting so much, you aren't even together.
It seems like you both want to force some kind of relationship, like your obligated to remain friends. The reason you probably still love him is because he never really got out of your life. I think, for any breakup really, it's best to not talk for a while. And I mean a while. Not a couple of weeks or whatever. You both need to move on with your lives. It won't help either of you get over it.
Tell him straight up that you don't want to talk for a while and trying to be friends isn't working for you. It'll help you move on. If he continues to contact you, be strong and ignore him
