Sounds like most of you gents neglected to have "the talk" (pre-nup).
It goes like this : "If push should ever come to shove, be advised that there is one thing in this world -- and one only
-- that you can do for
me that I can't do just as well myself, if not better."
"And what might that
be ?" (Self-assured smirk).
It clarifies everything wonderfully.
