ya move on from this guy.
don't have any contact with him. he is playing with you and doesn't intend to be faithful to you.
You are bright and intelligent and can do better than him. join a class to take your mind of things like a sewing or knitting group where yoiu can meet other women and have some social support. I don't think you need ot meet men right now as you are still hurting. Just look for some good girlfriends to chat with.
take care.
