Don't be surprised by her anger, a lot of WASs get angry because of positive changes they see in the LBS that they wish would have happened years prior.
Her anger in this particular case is probably also a product of guilt/resentment that you are doing okay financially and emotionally.
I think you're right. Just hope she can overcome it.
