Homie Hopping

I'm just gonna get straight to the point. I fucked my ex boyfriends best friend when we broke up as revenge for him cheating on me but I'm pregnant now and I know it's my ex's baby because I'm too far for it to have been his friends but now he's denying my unborn. When I first told him, he was happy until he found out I slept with his friend and then he left $300 in my mailbox for an abortion. The very next day his friend called me and cursed me out for not "telling him about his baby". I'm just confused and I just don't know how to handle this situation. The father of my child doesn't want to be apart of its life and someone who isn't does and I just don't know if I should allow him to love my baby despite its DNA or what... Ladies please help.
