Often times, the W will put the spot light on whatever she can find to make the H appear guilty of the same thing she may have done. She will accuse and blame, and blow it out of proportion. It gives her a sense of justification.
Stay focused on your goals, and whenever she digs to find whatever she can to pin on you............just shake your head, give a small laugh, and move on. You are not required to give an account of nonsense.
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!
