I want to ask my husband to stop playing video games
Why do you think he has to stop playing video games.
Because i think he is addicted! And I want to address that issue before it becomes a problem
If you feel this is an issue of his then you are free to communicate this to him. Video games could without a doubt make it more difficult to spend time together or for your husband to be productive.
That might even support his addiction further and doesn't solve the problem. Also, I am not interested in playing video games.
Compromise is important when it comes to relationships. Just communicate and decide on whatever makes you both happy.
