Relationships rarely break because of one big event. Far more often they wear out in small things: a question that was never asked, a familiar tone of voice, another evening spent side by side but not together. The good news is that they are repaired in small things too — and it does not require your partner to go first.
Games are fine. They are a way to rest, to stay in touch with friends, to feel competent in a place where life is not offering much competence. The number of hours on its own tells you very little. The question is not how much you play, but what happens to the rest of your life while you do.
"I'm just tired." That is how the conversation often begins — and then it turns out to be a conversation about burnout. The difference is that a day off helps with tiredness. It does not help with burnout. The weekend passes, the holiday passes, and on Monday everything inside is the same: empty, heavy, and you no longer know what any of it is for.
