I'm no expert, but I don't really think you're going to have much luck convincing an abuser that he is an abuser.
Maybe it would help to have some individual counseling. Take some time and talk with a therapist in order to confirm your feelings and be sure about what you really want.
In the meantime, you don't have to rush the divorce if you are not ready. My divorce was pending in the court for two years before I finally submitted everything to make it final. Check with the court clerk and find out how long it can stay pending before they dismiss it.
Also, it sounds like it would be good for you to go no contact. You can enforce that boundary if you want to. You don't have to answer the phone just because it rings. You could change your number, too. You have the right to take some time and work on yourself. You don't need his permission to do it.
