Have you read Divorce Remedy? If so, have you re-read it recently? I found comfort in re-reading it when things got confusing. And I'd usually spot something that I hadn't tried before, or that I just needed to hear again.
I suspect you may need to back off for awhile. Since he told you that he wants to move on, now is a great time to focus on yourself and your daughter. Work on making a wonderful future for the two of you. Plan projects together. Make your home more for the two of you. Ect.
I also suspect that he's confused about what he wants. If he was drawing closer to you then you were definately doing SOMETHING right. Can you figure out what that was? Try to do more of it when you are around him?
