Blame Leora. All she has to do is talk to him and show him what to do to be a better lover. Instead she says nothing. And because she says nothing, it either means she really is satisfied or she doesn't care. And if it really was a big deal, she would have left him. In any case there's no reason to feel sorry for her and she's the only one to blame for her dissatisfaction. People here just make more of a big deal about it.
Do you think that maybe she actually DOES love him?
