Married Couples and CRM (followon to Courious Crash)

What I am trying to understand is, how a husband and wife, both pilots,
would not challenge their spouse's decision to press a situation which
might lead to an uncertain outcome?

(Taking this thread into a new direction)
Ron and Margie, Jay and Mary, and the Tcraft couple are the only married
couples who use this forum that I am aware of.
Maybe there is a new thread, do spouses that fly together use a
challenge and response type of CRM when they fly together?
What type of resolution do they use?
If either one or the other expresses a concern, do they land and sort it
out?
Does one or the other have overriding veto?
