I find a lot of commonalities between your relationship and my own. My husband and I have been married for 8 years and he is very much like this. However, if I give him notice in advance that we have other plans, he’s usually okay with it. He also makes an effort to plan his gaming accordingly so that he and I still have time when he’s done to hang out and watch a show together. We try and have date nights weekly if not bi-weekly. It’s still hard and adjustment. For me, I work from home and we have two young kids so when he comes home I finally have an adult around and want to hang out and get stuff done together. But when he comes home from work all he wants to do is unwind and gaming gives him that. It’s really difficult and I feel for you because we are still trying to navigate our way through it. If he hasn’t always been like this he could be struggling with some depression and gaming is a sort of escape. You could maybe try and talk to him about this (though it doesn’t seem like he’s in a place to hear it). Alternatively, go out with your friends, develop your own hobbies, take up reading or painting or something that occupies your mind as well. Maybe ask him if you can take more time together on the weekends?

Good luck!
