Well, marrying someone and the taking their money in a divorce may be immoral, but it’s not a crime. In fact, it’s often statutorily enforced.
I once met a very rich woman on a cruise. She actually lived next to Bob Hope. She joined our table at the Captain’s cocktail party for repeat cruisers. She had more diamonds on her than a jewelry store LOL. But dang it I was already married.
Not even marriage.
Some gals just date for meals. Like hundreds of times a year. Brag about it on their online accts.
Or date a guy and he helps them out financially, and then after that problem is paid off, dumps them. Just dated him for money and help, then dumped him.
Men are just utility for women.
