Need some advice..

So after a huge fight with my boyfriend?.. I'm not quite sure if we're back together yet.. and a month without speaking, (I'm almost 17 weeks pregnant) I decided to let him back him in my life. The argument was through text, never again. And it ended with him threatening my life and very disrespectful words. I can't unlove the father of my baby.. But it's very hard to get past all the hurtful things he said. Im trying though because he's promised to be there for me and be patient even if I decide I dont want to continue a relationship. But I just want him to try harder to show me he loves me. He doesn't tell me he loves me that much and he doesn't show it. I feel like he has alot to prove here and he should be kissing my feet for letting him back in (joking obviously) I just don't know what to do. I'm so sad
