Hi, Im a single mother. My situation is as follows. My son is 4 years old now. His father walked out on us when he was about 6 months old. Has not seen him since. His father fell upon some trouble {drug addiction, homeless etc}. He has made about 2 or 3 payments of $100 the first few months, then no more. We are not married and he is not on my sons birth certificate. Years went by and we heard nothing from him. A few weeks prior to my sons 4th birthday, he shows up.. wanting to play the role of "Father". He wants to be a part of my sons life.. which I have no problem with... BUT I do NOT trust him with our son. I aked him to wait until I feel he is trustworthy. Instead, he went around and is taking me to court. I do not want my son to be with him alone, due to his fathers lifestyle, roomates, history etc. What can I do?
