I have a question for you. Considering the troubles your M has experienced....why did you not cut off contact with Chrome when he told you he had feelings for you? Surely you saw the slippery slope you were on. I'm not beating you up...simply asking why you would go there.
BTW...I appreciate the fact that you came clean on here.
I too e-mailed with him away from this BB...but kept a firm boundary (I believe Chrome would back that statement up.) There was absolutely nothing I typed to Chrome that I wouldn't have readily shown my H (in fact we discussed his situation). So...would you have shown your communications to your H? If not...I would have thought that should have been a huge red flag for you too that you were heading down that slippery slope yourself. Perhaps I'm reading too much into your post to Chrome...but when you mentioned him having feelings towards his W, OW, and you...from the tone of your post I got the feeling it was mutual.
I absolutely do recognize now (knowing what I do at this point) that e-mailing him individually was the wrong thing for us to do. It made it too easy for him not to come here and allow us to collectively support him. But then he pretty much tied our hands on that anyway since he only provided partial information to us.
