Mike,
This one is real easy. He allowed his name on the birth certificate. That legally makes him the father, and therefore legally responsible. I would also think that the 'intent' he showed with visits, money, gifts and such did not help his case either.

Being gay has nothing to do with it. A straight couple could be in the same situation if they used a sperm donor to get pregnant, put the donors name on the birth certificate, and then allowed contact between the donor and kid.
