Abortion or keep?!? Help ladies!

So im just over 3 weeks pregnant to my ex boyfriend, ex best friend=(baby's dad). When it gets out there will be so much drama around this as the babys dad already has a 8 month old baby to another woman who left him for another man.

I have tried to speak to my baby's father to get him to help me with this but all I got was "this is your choice he can't tell me what to do because it will effect me more then it will effect him." And "I'll man up on what you decide"

I've wanted a baby for so long but the situation is difficult please help ladies!!!!
