Sorry you are still struggling with W. I'm sure it's making you crazy.
Cadence offers some excellent advice in my opinion. I think if you can detach from obsessing about W and when she changed her password etc, you will feel a little lighter. It really does take practice though.
It seems like you are stuck in a cycle, some things have to change in order for something to change ya know? I think the change has to start with you, because your W doesn't seem too concerned at the moment.
