FWIW, I want you to know that in bringing up the 2nd EA I wasn't trying to judge you...in fact I was trying to leave your name out of it. BUT, Chrome is just as culpible for the "friendship" spiraling out of control emotionally as you are. Why? Because Chrome knows himself well enough to know he cannot have a close friendship with a woman without becoming attached to her emotionally. He knew better than to do what he was doing at the time he was doing it. He knew, just as you did, that if he had to hide the friendship...there was already something wrong with what he was doing. Neither of you were going to be able to get to the place in your marriage with this emotional connection between the two of you....simply wasn't going to happen.
My point in even bringing it up was to say that Chrome needs to be completely honest with his wife and come clean if he has any hopes to gain her real trust....for her to trust him enough to become vulnerable enough to reach that state of intimacy he craves. Personally I believe he needs to do this in a therapists office with her too...so they can both receive immediate help working through these things.
