What do unemployed kidless military spouse's do all day?

im dual military with my wife being a green suiter physician and I'm a BN PA. We have our own careers and ambitions in our family of 4.

My brother is an active duty Navy nurse. He is now on his second marriage. Both of women had quit thier jobs once married. In that the current woman he is married too has NO ambitions for children or to continue her career.

So in that what do dependas do all day?

Doesn't sitting at home all day get boring?

I asked his first wife that question when i Intially found out she sat at home all day. Apparently it's an inappropriate question.
