he probably senses the power he has over you and it makes him feel good about himself that he can click his finger and you come running. Then, when he's satisfied/come to his (twisted) senses, he pushes you away cos he can and for effect. I knew a bloke like that when I was a teenager who admitted that he liked to make a girl fall so completely for him and then play pull/push with her, toy with her feelings and the more he did, the more the girls loved him. Be strong and tell him to F off. Your boat has sailed, you're (happily) married and he's still waving on the quay! Sad loser! I bet he treated you badly when you were with him... not like physically but played with your mind and that.
