complications with the father😒

Hello everyone! I met this guy (who is the father of my baby) back in October at work. Him & I have been friends until back in February when I found myself crushing on him. We went on dates, talked on the phone every single night, & enjoyed each other's company. He just turned 19 & I'll be 21 in October. When I found out I was pregnant, at first he was happy. But everything made a wide turn & his whole mood changed. Two weeks ago he's been bullying me about getting an abortion, making me cry & hurting my feelings. When I told him last week that I wanted to keep the baby, he said he would be there for the baby but he could care less about me. He's still bullying me & hurting my feelings till this very day. Stress is not good for the baby & I think that's what he wants me to do. Do everyone think that he'll eventually come around? Or will he continue to be childish throughout my whole pregnancy. I would love for him to be there for me, but I can't continue to be bullied like this on the daily basis. Please help! Thank you.
