Here's the thing. Reading your profile, it sounds like you'll want a few places to base yourselves in. A few in the US, and another in France.
That kind of thing supports having high NW, so I perhaps understand your spouse's anxiety.
Conversely, you are aging. If you are dreaming of going to France to hit the Alps and ski or hike, maybe now is the time. Don't delay!
It is a trade off. Yet, a NW of 8-large along with that huge pension makes me believe you are ready, and you both need to continue talking.
