Is adoption the best choice in a situation like this

Disclaimer I KNOW I should’ve cut him off a long time ago ok. I know we shouldn’t have had sex again.

But I don’t. Know. What. To. do.

I haven’t even told him yet cause I know he will probably just disappear again... I just want it to go away but I don’t want to cause more trauma and pain to myself with another abortion or even adoption yet to parent this child with a father such as him might cause the child unnecessary trauma... so what is the right choice. Seems like no matter what I’m selfish. Selfish if I get an abortion again. Selfish if I place the baby for adoption. Selfish if I choose to parent it knowing the situation is less than ideal.....

Update. He told me to get an abortion and never talk to him again.
