I don't know, but I know. She has to be involved with this guy on some level. Over the weekend she decided she would go to counseling. Today I ask her about a specific date regarding seeing the counselor and her response was "I also called a mediator. I'd like us to meet with one." When I suggested that we should see the counselor first, her response was, "I haven't made the appointment I just called for a consult."
Its clear she's in a different place than I am. I'm going to see the therapist with her just to see if she'll admit that she's having an affair.
Cheaters don't admit anything they don't have to. Sometimes they do but it's rare. MC is a complete waste of time and money if she's going to lie. That's why you have to confirm one way or another before you bother. At a single male co-worker's house until 1:30am? It's confirmed for me because it's true but if you need more proof then get it by any means necessary. It really does determine your next course of action.
