Trauma dump!!

I’m 14 weeks pregnant and I’ve gone no contact with the child’s father. He has BEGGED me to have an abortion since day 1 even paid 1k for it. I told him no and I would use the money for something else. He gave it to me and told me that I’d come around. He told me he can’t bare to explain to his 8 yo daughter that this baby and her don’t have the same mother so he can’t bare to live with disappointing her. Boohoo. He was separated when we met and was the sperm donor for my last child. Now, this child was unplanned and accidental on both parts, we used protection that broke. I had an abortion last September with him and cannot bear to do it again…it was horrific and broke me. He has since gotten back with his wife and is now saying he doesn’t want to risk messing up things at home by being in this baby’s life. His wife found out about the abortion last September but, doesn’t know about the 1 year old. He said he will sign the birth certificate when the baby is born but, I’m starting to believe he won’t even be reachable. What do I do?
