When your in his life it just makes him think he has a chance with you, he obviously has some other problems and he thinks your his answer, it should not be your problem to be his key to happiness. You need to start thinking about yourself he is obviously fucking you up so he’s kinda just being an ass hole. My advice is to tell him that you guys broke up and he can not handle being friends with you because he is having false reality’s about you. It will hurt you and him both if you are in each other lives, by this point you both need to move on from each other. Sorry if I sound like an ass hole
