If this new man really truly loves you then he's going to give you the advice he thinks is most beneficial to YOU.
If YOU do not want an abortion, then do not get one. Period. Abortion is not something to be wishy-washy about. You refused to get an abortion for your husband... so don't get one just to hide from your new love! That would be hypocritical of you and I think you feel that way too. You'd just be aborting for a different man. If you want an abortion, do it for YOU, and no one else.
You are not a bad person! You were abused and now things are better. I think if this man truly loves you he will be fine with raising the child in a safe environment, far away from the child's abusive genetic father.
If you have the resources to care for this child and if you would love it, then I say do what your heart is telling you. You can PM me if you'd like to talk about anything!
