But the fact that it's all happening at her work which she isn't going to leave anytime soon is killing me. How in the world are you gonna get the EA out of her head if she sees him on a regular basis.
And how should I actually deal with her when we see each other? I am just plainly mad that she lied to me and the trust is completely gone.
So you're saying that they work together, that you are often away, that your trust is gone... and that you believe her when she says it isn't physical? I don't know what's going on, but I observe many signs that you should prepare yourself for the worst immediately.
By the way, part of my advice to you comes from the reaction of 25yearsmlc here when my W confirmed her OM to me by email. It might be instructive for you to read it, as it is advice from the vets on a similar situation.
