TRUST ME, when I tell you I know how bad you are hurting! As far as your daughter is concerned talk to him and be straight forward. Begin by saying something like, I want to talk to you about -your daughter's name-. This has nothing to do with our relationship, I promise. I am not trying a desperate attempt to keep you but my daughter has become our daughter over the past years and she should not suffer because of our relationship problems. I would like for you to be in her life. I am not asking you for any money like child support or anything like that but I'm asking for her sake could you continue to be her dad and if not don't say that you will and then disappear from her life that would be too hard for her. Say something like that and just see what he says, the worst that could happen would be for him to say no.
