I'm trying like hell not to spiral. I even told her I needed a time out (as prescribed by our therapist) because I was starting to spiral. I want to be there for her, but I can't sit there and make her feel better about OM.
I think that's healthy, and appropriate.
My mentor here on this forum taught me "Never shelter an adulterer from the consequences of their adultery." I think she needs to feel this, and while you can validate her PAIN I don't think you should swoop in to RESCUE her from from it . . . especially if she's saying it simultaneously with "I have never loved you" ???
