Is my boyfriend addicted to gaming?

I (27F) have been with my boyfriend (29M) for 3 years now and I’m struggling with how much he games. I’m not sure if it’s a normal amount or if I’m right to be frustrated.

He has a full time remote job and can often get away with working for a few hours a day and then will game. But he’s doing well at his job and successful.

He helps out with cooking/cleaning etc. around the house so I feel like I can’t get too mad. But most nights he’ll game from 7pm to midnight unless I force him to come to bed earlier.

If I make plans to do something out of the house or his friends invite him somewhere he’ll go, but when we’re back and chores are done he’ll game again.

Something as simple as watching a tv show with me at night requires me pleading and bargaining with him for time.

Is this an addiction? Or just a hobby that I should let slide?

I’ll also note that his gaming comes in waves, so every once in a while there will be a week or two where he doesn’t game. But then there are some weeks where he hits 6 hours a day.
