Or maybe she doesn't like being lied to. Ya know, "That's it honey, I'm retired and the rest of our lives will be for us." Then two months later, "Never mind. Honey, you can wait". That tends to tick off a spouse a little bit.
She's pretty controlling, so it was probably something along the lines of, "I TOLD you to stop playing that dumb game and stay home so I can keep an eye on you at all times!" And she probably wants to keep tabs on him because she knows that she was screwing him while he had a pregnant girlfriend, so what's to stop him from nabbing some strange on the road?
