frustrated

My husband and I have been fighting constantly and tonight he told me that if we split up and I took him for child support and visitation, he'd walk out of his child's life because he doesn't want to get "fucked over" like what the fuck dude. I don't think the father of a child should be able to even have that sort of choice at all. he told me if we couldn't agree on something not to even bother putting him on the birth certificate. any advice is appreciated.
