A day in my life

I live at my grandparents. I was on the phone with my boyfriend. Who is staying at my dads. Last night it was gettin late (about 10) so I asked him to go to bed when he gets home. And he said I already planned on it. But NOPE he wants to drink with the neighbor and his cousin. He turns off his phone. Doesn't turn it on till I texted the neighbors wife saying that his dad was trying to call him. (I told him the situation) not to mention i was balling my eyes out until 12. He still hasn't called me because he's passed out on my dads couch with a hangover. I don't know what he did last night. So I kept texting him I was done. Not to mention I'm 6 weeks pregnant and he just out of the blue started doing his own thing. What should I do?
