Some WW's do mean and hurtful things, and they will lead people to think the H is the bad guy.......to justify herself. It's as if a total stranger has replaced the soul of your W and just borrowing her body. For your own sanity, you may have to think of her as being a completely different woman.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
