Stupid questions just send you down the rabbit hole. This is a stupid question.
Why don't you ask instead, “How can I make my wife smile today? How can I make her feel loved and gotten and respected?” and then go do that.
Maybe she doesn't want someone better. Maybe she just wants you to be the best you you can be. “How can I be great today?” might be another good question.
Or “How can I be the type of person that my wife wouldn't even think of looking anywhere else?” You know, the person you were that she married. Bring that fun, that sense of play, that excitement, to today, and maybe you'll have a chance.
And if she doesn't appreciate all those things anymore, that you both brought to make it fun and alive and exciting, maybe it's time to move on and find someone who does.
