Silent treatment

So yesterday my SO did something that hurt me pretty bad, instead of saying sorry or trying to talk he went to the bedroom for the rest of the night, today we haven't spoken really at all until I told him how I felt and how it made me feel.. stuff like that. well he is still pretty much not speaking to me I'm not sure what to do, alot of our arguments I end up apologizing but this time it cut pretty deep. What should I do ? What would you do... I'm pregnant also so it hurts alot more, I've pretty much just been in the bedroom by myself. And I really miss my family back home so I think that's making things worse.
