no judgement please

I need help deciding if abortion is right for me. my bf and I had a good relationship until I found out he is still in love with his ex and she threatens me and both talk horribly about me. so I found out I was pregnant he was somewhat excited he always wanted kids but as soon as I found out it was a girl he lost all interest won't touch my belly just nothing so I'm having a hard attaching to the baby or being excited at all. I considered adoption but the dad said he doesn't believe in that and doesn't want to deal with all that. in the end I feel abortion is best we don't have a good relationship and I don't think i could handle joint custody especially knowing his ex would be raising the kid too and she would try and take the baby from me. the whole situation is really ugly and I don't want a baby in that. Sorry for the rant but I have no support only judgement from friends and family.
