Sounds like your W is losing her grip and it is making her nervous. She is trying to maintain control over you. Although it sounds like she is accusing you of "making it ugly", she is actually threatening that she is going to "make it ugly". Can she? Truly? The vets will tell you that WW is a "paper tigress" and that our fear of WW is based on a faulty perception of them. I *hope* a vet will chime in about this. I would never respond to this because you will not convince her otherwise. She will blame you regardless. Everything she does is to justify her own improper actions.
In the meantime, keep your chin up and consider it the ramblings of someone who is completely removed from reality.
