My ex boyfriend and I have a child together and he is on felony probation for pills and he was shooting crystal meth when my daughter was first born and I don't know if he is still using it but he does have some weird marks on his arms and I know for a fact he still smokes marijuana. I told him to go to the hospital and sign the birth certificate and he didn't so I was wandering does he still have rights to her even if he didn't sign it because I have this weird feeling that he's not going to change antime soon.
