Am I the a hole for having a kid with my bsfs bf at 15

I am 28f (right now) I was 15 at the time he was 18 at the time he is 31 right now. My daughter is 13 right now (read my other story). My bsf was always toxic to me but I loved her and she loved me at points. She had just gotten a bf and hid him from me bc she's toxic like that. She and him always skipped school to smoke and do coke together but I didnt know that until after I had my beautiful baby girl. My bestfriend finally told me after 3 weeks and introduced me to him and we clicked instantly he had that sparkle in his eye that made you fall in love instantly! We went out for dinner to the best restaurant just to get to know each other and he paid we got very drunk but I knew what was going on. He took me to his house his parents weren't home. We were laying on his bed until he put his hands in my pants and took them off. I let him do it because I liked him alot then we got intimate and next thing I knew I woke and went to the bathroom mind you I had my period at the time. I thought why am I not bleeding is it bc we got intimate or am I pregnant. I told him and he went to get a pregnancy test and he came back and I did it. I told him I was pregnant he told we are not keeping it. I started screaming at him telling him I'm loving this baby no matter what. I told my bsf and she told me to go to hell and f off and kms and the baby. I still hate her to this day bc of that. 9 months later I had my beautiful baby girl violet rose semtly.
