There is a time to nag and a time to just give the silent treatment, for the right reasons. But if she's just going to nag just to push his buttons, then she's the one with the problem and needs to learn how to can it sometimes.
If wives didn't nag at the husbands, he wouldn't get some of the chores around the house done either.
I only nag and bish online, and nope, for my own good, I don't take any men in here seriously at all. Peace.
