My son is 13 months old. In the past 7 months, my ex had seen him maybe 4 or 5 times. They don't know each other at all. My ex doesn't even call or help me out with my son. In January 07 I asked for him to sign him over, and he said no. His name is on the birth certificate, but we were never married. I live in TX so some laws are different. I'm not sure of all of my rights or his. My fiancée wants to adopt my son. How do I prove that my ex is an unfit father? He has also been to jail 4 times in 3 months! He does drugs and sells them. He doesn't care about me or my son. Help me please!
