I can’t take it anymore

I’m 22 weeks pregnant and my bf doesn’t ever get off his stupid video games!!!! He’s gonna be 25!!!! I honestly do everything and if I ask him to do something I have to ask him multiple times or I just end up doing it. He gets home from work and goes straight to the games. It doesn’t bother me sometimes because i do like my own space but it’s getting to the point where he literally sits on there from when he’s off work till bed or from when he wakes up till bed. It’s like pulling teeth when I ask him to go somewhere with me and I usually end up going alone because of it. It was never this bad and I don’t know how it got to this point but I don’t know how to address it because whenever I do he just says it’s the only thing he likes to do. He NEVER takes me out or surprises me and he doesn’t know what is ever going on. I guarantee he doesn’t know I have an ultrasound Monday, he probably doesn’t know how many weeks I am, and everything else. I just don’t know what to do. He’s not a bad boyfriend for any other reasons and he shows me that he loves and cares for me all of the time but he doesn’t get off the games to ever do anything let alone do anything nice for me.
