Listen to your wife here, the subtext of that comment might be that your employment is straining your relationship. I had to learn the same lesson recently, and with three kids, you have too much to lose to ignore any warning signs there. Have you ever sat down and really taken a look at what lifestyle compromises you'd have to make? It might be fairly superficial. Cook at home a few more times a week, make it a family thing. It isn't all downside living a bit more humbly.
