That is a difficult question to answer as we don't see a lot of WWs who continue doing it. Mine for instance, has never ever not once asked to do a family trip or anything like that (or shown guilt for that matter), so yours is a bit out of the ordinary. My best guess is that you somehow allow her to continue. Is she still with the original AP, by the way?
I just noticed your question on why the break ups of shorter Rs after D hurts more, a couple of posts back. I stumbled upon an explanation for that recently (as I have been going through something similar). I'll see if I can find it again.
