Try desperate, dear. These people, mostly men, are lonely and desperate for affection. The Pretty Woman effect goes both ways. These poor fools believe that if they shower enough attention and buy these whores enough shit they will become that special person in their life who gets to have a say over their emotions. They want to reform them, make them love them.

You can't reform a whore with gifts. They don't value themselves as you would, and view relationships as only a means to an end. By the time someone turns to this kind of act, they aren't in any position for a real, healthy relationship anymore. It takes time to overcome that, not cash.
