Partner walked out and wants nothing to do with the baby!

Catherine
So I'm 17 weeks pregnant, it wasn't planned. My now ex partner has decided he doesn't want it and has walked out on me saying he wants nothing to do with it and thanks for fucking up his life!! He has 2 kids to a pervious marriage and I allready have one!! I am beside myself on what to do I don't wanna do it alone again I just can't!! Before he left me he was trying to make me have a termination or give it up for adoption!! He has been nothing but nasty and abusing since the day we found out I was pregnant
