Good grief!
In the first place, it is ridiculous to claim that Haley's mom hates her. Her mom cares deeply for Haley, but is concerned about her choices, and doesn't trust her judgement. Why is that? Because Mom knows about Klaus. So why didn't Mom do something about it? Because Haley told her mother the exact same thing that she told the MC at first, that IT WAS ALL HER OWN FAULT. We don't know the exact conversation that occurred between the two, but some pleading was obviously involved. The result has been a mother's deep concern about what will happen with her daughter, which is why she implores the MC to watch over Haley.
Distrust, yes; hate, complete rubbish!
Secondly, I do believe that Haley, while not wanting to do it (or continue it) with Klaus WAS aroused by the act itself. For that, I in no way place any blame or disrespect on Haley whatsoever. It was a natural response, even in such a deplorable situation, for a female with strong sexual desires. But it is one of the reasons that Haley has to go through therapy, since I believe that one of the reasons she blames herself, and has been so reluctant to talk about it, is exactly because she felt something physically while with Klaus. Haley needs to realize that in no way was she to blame for anything that happened with Klaus, and the therapist, together with the MC, can help her with that, if she will let them. Haley already has acknowledged that Klaus has hurt her; now it's time for her to shed her self-blame.
If you had actually read any of my past posts on this thread, you would not have tried to paint me as in any way thinking badly of Haley's character. Try a erecting a different strawman next time.
