Deadbeat baby’s father.

How do I deal with a deadbeat? He refuses to have anything to do with my baby girl but he doesn’t mind asking me for sex. Doesn’t wanna terminate his rights, doesn’t wanna pay child support, doesn’t want me asking for anything, doesn’t want his family to know about her. I had sex with him ( I KNOW IT WAS A STUPID IDEA I BEAT MYSELF UP EVERYDAY) because he said he’d terminate his rights, if I did. We ended up getting into an argument while I was looking for the paper for him to sign he left My house blocked me on social media, changed his number. Idk I feel so low and stupid that I let him do it! Should I even pursue child support?
