I feel so alone

I’m 9 weeks pregnant and my fiancé and I have been fighting nonstop lately and he just acts like he couldn’t care less about my feelings. We were fighting last night about something he did and he walked out of the house so I called him today to see if he was coming by so we could talk it out and he said no. I told him if he doesn’t come by and talk this out with me then we’re done and all he said was ok. I’m heartbroken and I don’t even know what to say anymore.
