If she wants to support a gigolo, that's her business. You don't really have to step back or withdraw from her. You don't have to pretend to like this guy either. Just stop telling her what you think he should be doing. That's not for you to figure out. Be polite toward him. That's all you owe your daughter.

Don't, in any way, enable the situation . . . like by giving her money. Invite her for Sunday dinner now and then. If she brings the boyfriend, feed him too. Expect that he acts courteously toward you and expect nothing more. Don't ask what he's done about finding a job. That's his business. If he's sponging off your daughter, that's her business.

In your situation, my fervent prayer would be simply, "Dear Lord, please let her not get pregnant anytime soon." Hopefully, before that happens, she will get sick of this guy leeching off her. When she complains to you about this guy, you might say: "Sweetheart, I agree with you that he's not a good catch. I happen to think you could do better for yourself. But, if you want to hang on to him, that's up to you."
