My wife and I are getting a divorce because she got so engulfed in online gaming.

Jeff, it is understandable to feel rejected when you feel your wife has stopped paying attention to you. And while all this might spell out as a crisis in your marriage, this is also an opportunity to recognize what may be lacking within the relationship  and identify what you can build on. 

If your wife is seeking community and validation from the outside, it may be because she feels she is lacking this in her life. It can also be that she may have been feeling isolated and unable to express herself. COVID certainly did not help with preventing people to feel isolated and disconnected. This may be your wife's attempt to feeling connected.  This can be a great opportunity to build on creating pockets of intimacy and validation within your relationship. For example, planning on doing activities together such as taking walks together as a couple, and not allowing any social media on these walks to allow both of you to interact with each other. She may be seeking to be listened and to be heard, so this may be a good time to work on your communication together.

You can also create intimate moments for communication by planning a date night, cooking together, when you both agree to stay off the phones. Address the social media issues with curiosity rather than as replacement to see what both of you may discover about each other's needs. or what you might need more of.

If this is about connecting socially, it might be the time to plan dinners or get togethers, going to church, or community gatherings  with intimate friends so you can both share and partake in community as a couple.

These few activities can do both of you a world of good connecting with each other, and with friends and community. If this does not seem to make a difference, it may be a good time for both of you to participate in couple's therapy. Therapy for couples can be a great way of identifying the reasons that brought you together, and in reconnecting. It can also address you concerns in a safe non-judgmental way, and open the door to safely addressing things that may be interfering with your communication and intimacy.
