I(25F) feel like my bf(32M) has a gaming addiction and it’s affecting our relationship

I(25F) feel like my bf(32M) has an addiction with gaming. The PlayStation beep is literally the first thing I hear every morning like it’s a fucking alarm. I have sat and noticed the pattern. He wakes up around 7am, spends 30m to an hour in the shower. He gets out, and hops right on the game around 8:30am. He will literally play and play until around 10-11pm at night. The only time he leaves the room is to eat and use the bathroom.

Every time I call it out, he always says something about how I’m “ruining his fun” or I’m “keeping him from what makes him happy” I’m 37 weeks pregnant and the only income he has is unemployment. I feel like his gaming is an addiction more than a hobby and it’s becoming an issue as he thinks it’s okay to play the game for 8-13 hours a day instead of looking for a steady job. What do I do?

Edit: We’ve been together almost 3 years. He had a steady job at first and everything was good, but since he has lost it like 3 months ago, it’s been rough.

TLDR: my bf spends 8-13 hours a day on gaming and he gets upset when I bring it up that it’s affecting the relationship and his productivity negatively.
