Should I consider his request of second marriage?

I was a virgin before I met this man, and honestly believed I would end up marrying him so I commited zina with him. Because of this I found it very difficult to let go and accept the situation of him lying, treating me badly and leaving me. I knew I should have cut all ties with him. I asked Allah to forgive me for all the wrongs I did during our relationship, however I still feel I need him in my life and cannot seem to forget and move on.
