I really need some support right now..

My appointment for the abortion pill is coming up in a few days and I’ve really been struggling. I’m at the age in my life where I do want a baby but I didn’t want it this way or with this guy. and the father knows I don’t want to be with him and he’s playing all sweet now but I know once the baby is born he will go full blown into the courts and try to make my life miserable. I wanted a baby with someone I really loved and cared about but I made a stupid mistake during a horrible time in my life and a moment of weakness. please someone give me some advice. I feel like a horrible person for wanting an abortion but I do not want to co parent with a guy I don’t like (not even really as a person) for the rest of my life and be miserable. help. :(
