I agree...Prudie blew this one completely.

It's sad commentary that the vindictive mother who managed to repress her own guilt over the issue, (and let's be honest...why would she be so upset over her daughter's reaction if deep inside it didn't cause her pain and guilt) should simply pass on her burden to her daughter and it somehow the daughter's problem "to get past".

While she may need counseling, I think she should let her mother know that she is doing it in full awareness that this was something that her mother brought upon her, and that it was very clear that her mother had used her as a weapon against her father. She should also say she hopes she finds a way to come to peace with it just as her mother reconciled with her father even if she can't discuss her own issue with her daughter.
