You will notice I did not say “if she can’t cook don’t marry her” I said “if she can’t cook, think long and hard before you marry her”... There was a reason I conditionalized this and it was not an absolute, and your situation is proof of that.
:) Whew. Thanks from all the women whose moms never taught them how to cook. Of course, competing in sports through my college years usually had me at a practice and nowhere near a kitchen long enough to do more than nuke something or stop at the cafeteria on the way home.
