You have good questions Mr Bond! Not sure how much she knows about...she knows of the times we've met in person. Not sure if she knows about the late-night phone calls or the multiple emails each day...
From what he says she is being nothing but supportive & patient. That she "knew" what she was getting into when she started messaging him. She has offered to step away from their R three times, which he says shows how much of a giving person she is. The physical contact hurt her (of course!) and she won't be able to forgive a 3rd time (it was 3 times, but he told her about 2 at the same time...)
Can't remember if I've already posted this, but I've asked him to no longer include any mention of her in his correspondence/conversations with me. I know she's there, I know he still doesn't know 'what' he wants. I don't need to be reminded. It only makes me feel like the OW and his backup plan!
