Help me please

I've never posted anything on here before. But I just need some reassurance on some things that have been on my mind. I'm not looking for a pity party just reassurance. 
A few months ago me and fiancé lost a baby. I was only two months pregnant. He went on blaming me for losing Liam (that's what we called the baby because we wanted a boy). He said that I should've rested more, not done so much housework, and other things. I haven't been able to get over that still. 
And this weekend we got into a huge fight. I told him I didn't want to be with him anymore but I didn't mean it, I was just so angry at him. He knew I didn't mean it and he forgave me. It's a long distance relationship. I'm starting to have thoughts about what I would feel like if we weren't together. I don't want to hurt him or lose him. My father hates him, I mean really hates him and my best friend doesn't like him either. I don't know what to do.
