My wife is not a gamer.
Worst, she doesn't understand why a grown man of 46 years of age would sit around a table playing some ridiculous game with 4 to 6 people who are half his age.
She has asked me when I intend to 'grown up'. I tell her 'Never'
While she may resent it or not understand it, we don't allow it to be a sore point within our marriage.
I was a gamer when she married me 23 years ago, so it wasn't like she didn't know what I did for entertainment.
She has accepted that it is 'Del (my first name) Thing' - my wife thinks that I am eccentric and weird. As I have told her - some of her activities I find equally incomprehensible, but I don't deny her right to do them.
As I tell her - I don't drink or smoke, watch sports, don't go to bars and strip joints, don't chase women or flirt. I am not abusive in any fashion to her or my kids. I don't have have a love affair with my car, motorcycle, or big screen tv - unlike other guys I have seen. I do laundry, do housework and make 50% of the meals and am a pretty open minded and informed guy when it come to feminine issues. My only social activity outside of doing stuff with my family (and my wife) is gaming.
In short, she got a 'great deal' - and she agrees, which is why she tolerates the gaming, even though she doesn't understand it one bit nor does she even want to understand it.
We don't let it be an issue in our marriage. We realize that we are individuals who have different tastes, even though we have chose to share our lives together.
