Not sure what i want to do ..

Hello! I’m currently 11 weeks and 5 days. I have an abortion scheduled for May 26th .. but it’s not what i want. The father changed his mind 10 weeks in and since then he’s been insistent i get an abortion. We aren’t in a relationship but things were great between us before i found out. It felt like we were working towards one. When i found out i was only 4 weeks and i let him know immediately, he told me to keep it and he was excited. Fast forward to when im 7 weeks and the hormones started going crazy and we got in one argument and his entire mindset changed. He barely gives me the time of day doesn’t check up on me or the baby when i mentioned abortion he asked how much. I scheduled the appt for him but now i’m thinking i’d rather be a single mom. Anyone that had an abortion for the father and not for themself? how do you feel now?
