should I be worried?

UPDATE: He came home 5 hours after he said he would. Claims he went with our friend to some guys house to check it out before she stayed there alone. I'm angry. He should have came home to his pregnant wife.
So my husband never does what he says. And tonight he lost his job, went to the bar and said he'd be home in a bit. I asked him to just come home and he wouldn't, said it would be just a bit. Well I just woke up 4 hours later and he is still not home. He went out to an apartment with a friend of ours who he once tried to have a relationship with.. I'm pregnant. Pissed. Sad. And just hurt. Does he even want me here?
