I feel that you need to gently, but firmly, state your feelings on this matter to him. Reassure him that you don’t want him to completely stop playing games, just that you would enjoy having one on one time with him for at least a few hours a day. As part of a relationship, is reinforcing that connection which was initially formed by dating, and building upon it. To me, his fixation of gaming screams escapism…As it is easier to avoid dealing with discomfort than to face it head-on (I speak from experience on that matter). He’s not a bad dude, like you said, he is fighting (or avoiding) serious internal struggles.
You’re welcome! Yeah, I’ve been in that boat before, reestablishing a healthier connection to games. Games to pass the time in a way nothing else can, especially if you have a dopamine/serotonin deprived brain…It might feel like he can’t stop at the moment, eventually, with gentle, consistent, and firm effort it will be possible. Getting him to the point where he can associate time passing pleasantly with you and other people in his life; this will go a long way of repairing not only your relationship, but, provide him with stronger interpersonal connections.
