My boyfriend wants me to miscarry

Though we have told both of our family's we are expecting a baby, the shock and disappointment of this baby has worn off of me and now I'm trying to be excited. His family is excited my family is excited. (Our relationship is coming to an end) but he has agreed he will take care of the baby and be the dad the baby needs.

However

He in the beginning he really wanted me to get an abortion. I did not. Now he is eagerly awaiting a miscarriage. I brought up a fear of premature birth during conversation with him and I, he even implied that would make him happy if the baby died due to prematurity.

I try to let it roll off but I'm going into my second trimester this week.. and I think it's just getting really mean at this point how do I handle this?

For those of you who will insist I can raise my baby without him I am a single mother of one already and regardless of what you guys think I am not equipped to do it alone.

I just really need advice on how to handle the situation.
