You can’t make everyone happy

so my ex boyfriend keeps threatening me to take my child when I gave birth and it’s scaring me to think that I could possibly deal with something this hard myself for 9+ months and not even get the surprise at the end ? I know he’s just trying to hurt me but its so stressful . I’m contemplating running out of state because I’m not going to just give my baby up like that . I feel like he wants thes reward but doesn’t want to work for it ? I just don’t know what to do
