The survey states that "gaming widows," whose spouses neglect them to focus on gaming, are dissatisfied with the states of their marriage. How that differs from corporate widows, football widows, or any other neglected spouse without a catchy title isn't really specified. Another conclusion pointed out by the survey is that when spouses play together, the marriage tends to be in pretty good shape. Who'd have ever thought that spending time bonding over a shared interest would be healthy for a relationship?
While we're all in agreement that your level 80 Paladin probably doesn't deserve as much of your love and affection as your spouse, if you hadn't figured that out on your own, gaming probably isn't the root of your problems. Just a thought.
