My ex-boyfriend has changed his mind many times on wanting something to do with my unborn child. I am sure he is the father, but we have broken up and I do not want anything to do with him. I find him to be very immature, he has anger issues, maturity issues, and alcohol issues. The worst of it all, he's in school to become a police officer. I do not want him to have any rights to this child. He has told me a few times he would sign over his rights and then he changes his mind. He says " We need to think about the baby here, not just you"... but I don't want my baby to have to deal with his issues either. What can I do to keep him from having any rights at all?
