Like nost I am much more of a homebody than my wife. She still “withholds” more than I do and I find it intolerable from a psychological maturity and fairness point of view and ask her to snap out of it. Since she realizes this is her short coming she does. Of course being an amateur psychologist I educated her gradually. My wife is the best but we are not perfect and should try harder than to put the silent treatment on IMO. (or other types of withholding). It is not healthy for the relationship which is more important than a house. Not saying this is your experience RD just my 2cents. I’d ask her to snap the hell out of it though.
Maybe there is more to the story. My wife dislikes my biggest short coming, my modest temper;).
Maybe next time you go out into the market be prepared not to vacilate so much. If I were her I would have killed you.
