husband is being an ass

Ok so for the past week my husband has been off work. He has been on the stupid xbox the entire time he will be on it all day and all night the one night he did not come to bed till 6am the next morning and will sleep till almost 11. Well he just told me he's about to get back on and I said no you can stay off of it for a little bit and he said no that he's getting on it that he can do whatever he wants and if I don't like it then I need to get the fuck out. I'm debating on if I should call his mom and let her know what's been going on cause she can usually get his ass right when he's being stupid but at the same time idk if I want to. I'm 13 weeks pregnant with our 3rd child and he's acting like a fucking kid and it's pissing me off
