Where There's a Will — Carolyn Faulkner

Hugh Calumet has had bad experiences with women who were just after his money, and he's very afraid that his father is going down the same road with the new nursing assistant who is caring for him.

His father, of course, thinks Lisa walks on water.

But Hugh finds out something very embarrassing about Lisa, the CNA, that he then holds over her head in order to blackmail her into allowing him to discipline and make love to her.

Once he realizes, after moving back in with his father and his new stepmother, that she really isn't a gold-digger, he begins to regret how he's treated her, although he can't quite bring himself to stop it, either.
