General, My Wife Wants to Remarry

"General, my wife went to make money again." "It's okay, go see if there's anything in the way that doesn't look good." "General, my wife has gone to take care of her parents' family again." "It doesn't matter, my wife is beautiful and kind-hearted." "General, my wife was angry this morning and punished you by depriving you of dinner." "It doesn't matter, I won't starve to death even if I don't eat. Go to the street and buy Madam's favorite snacks to calm her down." "General, my wife is remarrying" "It doesn't matter,..." "What???" The soldier who came to report only saw a black shadow flashing past in front of him, and his general had long since disappeared.

But why did the general's wife remarry someone else just two years after their marriage?
