Help...termination of parental rights hearing in two weeks!!!

To make a long story short......my husband wants to adopt my daughter, biofather is contesting even though he has had no steady contact ever!!. He did see her for a few months two and a half years ago, and has not paid child support since. We live in CA, and the law states that we have grounds for abondonement, in fact we had a social worker come out and interview us all. Her recomendation is that the bf rights be terminated. What scares me is she says that the judge can rule against her and chose not to terminate bf rights. I want to be prepared when we go to the hearing, we are doing this without and attorney. So is there anyone out there that has been in a similiar situation? I'd really like to know what to expect when we go to court.
