If your wife is basically blackmailing you to run games, that's called an abusive relationship. It's not roleplaying games you should be worried about, it's your personal life. You aren't burned out from too much gaming, you have people in your life that are emotionally manipulating you-- your wife, all the teenagers in your neighborhood you've had to keep running games for in many of the threads you've written about in the past several months/years, apparently an entire wedding party. You have been unhappy for years now (cause we've seen it in all the threads you've written) but you haven't been able to get loose from the knots you've been tied up in.
What you need is to see a therapist, not worry about being burned out on D&D.
