I do get the anger stemming from frustration. At the end of the day though, work through your anger in positive ways, not directed at your W and what you think of her actions or words.
Maybe one day you will understand that she is doing what she THINKS is "right" and is doing the best she can with the tools she has.
It looks quite clear that you really should be working on detachment. Do you understand what detachment is and how it might work for you?
