I had a similar situation my daughters father left even before she was born. At the time I was 5 months pregnant. I had no choice but to collect welfare. The state of NJ ended up going after him for the support. When my daughter was 5 years old he took me to court for visitation. I refused and demanded his visitation rights be taken away. The judge agreed and he still pays child support til this day. She is now going on 14 years of age. Good luck with your case.
