I have a suggestion.....hindsight being 20/20 and all. I wanted desperately 2 divorce my husband when our daughter was 3 years old. She's 14 and we're still as hostile as I think 2 people can be. Daughter is a basket case. Looking back, if I'd of divorced him when she was little, all these years of fermenting hate wouldn't have probably happened. Maybe you feel somewhat threatened or whatever that she wants to spend time with her Dad, but let her. As long as he's a good Dad, encourage her. An occassional supper out, for the three of you would be good, but I think you need to maintain your independence and let his visits, except for rare occasions, happen somewhere else.
