PREGNANT BY A FLING 😖

I’m so lost idk what to do guys 😞 me and this guy I had been talking to messed around, I knew when he was about to finish so I went to get off him (I was on top) but he wrapped his arms around my waist and held me down. 3 weeks later I find out I’m pregnant. (Wow it really only takes one oops). He’s very adamant on abortion because we’re not in a relationship. I contemplated it for a week and half and I just can’t bring myself to do it. So I told him I’m keeping the baby and now he wants to sign his rights away. My brother is very upset about the guy not taking responsibility, my brother wants to adopt the baby so the guy can sign his rights away. But then I won’t be able to put him on child support and he really won’t have to take responsibility. Can y’all please give me some advice. I’m struggling so bad with this.

I’m already beating myself up for getting myself in this so please don’t be rude.

(Not to mention I have extreme pcos and never imagined it would be this easy to become pregnant I thought I would need fertility help)
