"Mentally mature men have no intention of cheating. Wisdom won't allow him to commit to a woman if he's unready to give all his attention to ONE. Cheating is for insecure cowards. It's not about sex. If it were, cheaters would just remain single to sleep with as many people as they wanted, then it wouldn't be cheating, and they wouldn't be cheaters. Cheating is about control. Filling insecurity. Cheating acts as a way to hold a loyal person's heart hostage, while the other behaves as if they're single. They could just end it, and sleep around, but they WANT to stay "committed," and make you suffer, to gain power from your pain."
