Both my sons have been engaged and date some. Many have poorly trained children, messy houses. Some love their circle of girlfriends more.
Men are out there, but some have been burned too many times.
One of my sons pays child support and can't afford to date much. In this world, both men and women have been burned in their search for love, companionship, and a cozy way of life. And the kind of women your boys find may be due to the kind of places where they find them. Look, there are good, kind, decent women out there. And if they're more loyal to their girlfriends than the latest boyfriend, it's probably because they are confident that they will get that same loyalty in return.
