I'll agree with the above two, Ginny should know what to do "for the good of the Weasley name and family", though I seriously doubt she'll do something like that. Besides, there's the question of what -that- would do to her kids; I cna think of several ways that could effect them, some good, some bad. One thing I'm sure of, though, I suspect her name is about to become mud in a number of places.
It was indeed a dark day for Molly Weasley and I suspect her bad times are just beginning now that her two youngest sons have lost all respect for her and they'll likely tell their remaining sibs and their father.
I can understand Harry's reactions, I think I'd be tempted along many of the same lines, but I hope he'll think it through as he is strong enough to make it and, really, his kids, -all- of his kids, are going to need his strength as a rock with all the turmoil that'll be going on around them.
I feel, too, for Hermione as just how much she & Harry have been played really comes home to her. I get the feeling she never stopped loving Harry, even after the potion made his behavior so horrible. In that case, this is going to be rough on the kids she had with Ron, too. I suspect Ron, this nicely mature Ron (good job with him, BTW), will be quite understanding and something amicable can be worked out.
