DW has "been there, done that".
We gave up a lot of potential income when she quit her government job to make the move to WV and she did have some angst about doing that. Both of us did, but me to a lesser extent. It works for us because I have a pension and I took a spousal benefit option on it so that she has a COLA'd income and medical insurance after I get "The Big Ache". Yes, that was a heavy hit on the pension but the quality of life is worth it.
As has been discussed before we found that once the basics are paid for a bigger income doesn't make us all that much happier. Traveling the world, the 40-meter yacht, Benzes, mcmansion, etc. were never priorities for us. She has what she wants most - an intact roof overhead, a full pantry, a reliable car, and time to spend with friends and family. She does not go shopping as a form of entertainment and in fact prefers to order clothes (when hers have holes in them) from catalogs/online to avoid dealing with stores.
She is, in fact, more excited about being able to give her nephew and his wife a new camera to take pictures of their children than she is about what to do for her birthday later this month. But I guess that's why I married her.
