Time to file? (Thanks BenB - part 2)

Hi again,
Just came home and W was in MBR talking on phone (most probably with OM).
I just went and had a shower and prepared to potentially enforce some sort of boundary. (During witch they hung up)
After I went to shave and she came to talk to me, Corona and work etc.
She talked some work related feelings and I validated a bit.

Afterwards I feel torn/ambivalent/unsure if I did the right thing.
As established in my first thread her talking with OM in my face and then talking about her feelings is hugely disrespectful. But she didn't know when I was coming home and they/she did end the call...
