I don't see the wife taking care of Sam; on the contrary, the guy is being annihilated. The setup at the strip club is meant to make him feel inadequate. I don't like it because the wife herself doesn't speak openly (although she does say that Sam is more resilient and better in bed than Leroy, and keeps that to herself). The truth is, Sam is young, good-looking, and a pleasant person, which attracts other women. Leroy was a porn actor, and Sam is better than him. I think if a woman comes along who truly cares for him and says good things to him, it's goodbye to the wife. And any woman who knows Sam and Leroy and can give a true opinion without manipulation will choose Sam. The wife mistreats Sam a lot, even considering making him perform oral sex on Leroy, licking his sperm because she takes him for granted, because he's afraid she'll leave him (his loving ex-wife).
