He left me two days ago

And all of his stuff is already gone from our house. The house we just moved into two months ago.. it's like there was no trace of him, or the fact that we lived here. All because I've been selfish and haven't felt good. 30 weeks pregnant with complications and high risk. And he leaves me out of the blue after a fight. Because he doesn't want to deal with my attitude anymore, that there is nothing between us anymore, and he doesn't love me anymore. All of his stuff is already gone. How can someone be so heartless.
