Missing work for video games?

My SO got a new computer for gaming last Thursday, well since then he has missed 3 days of work. He has told me that th jobs he had got canceled, I was suspicious so I went to look at his texts from his boss. And he had deleted thm? I know I shouldn't snoop through his phone but that just made it even more suspicious. I am 9 weeks pregnant and work as a bartender and go in to work nauseous, tired, vomiting, with migraines so it really pisses me off that he would miss work because he stays up all night playing fkn video games, and as soon as he opens his eyes he's right back on it. What would you do?
