An easy way to weed out bad wife material is to be an alpha, and say, “no” and expect her to submit to you. If she gets upset at hearing “no” after a few times run far far away. However, if she stop nagging or accepts “no” she will respect you.
If you're a true alpha, you'll break up or divorce her the minute she stops respecting you for good. Just think about it. Do you think Donald Trump would put up with that from his wife?
