W is very sensitive to any behaviors which could appear as controlling. In fact as I research this and listen to her, this is really a big core issue with her and is the primary reason she feels she needs to separate....to get away (unless the EA is continuing). She feels that I am not aware of many of the subtle things that I do.
DMB,
Unless YOU genuinely think that this has been an ongoing issue for you throughout your marriage, and/or there is a prior history of your wife sitting you down and conveying this complaint to you PRIOR to her recent walkaway/wayward behavior . . . do NOT put any stock in this. It's just typical wayward BS "script."
"You're too controlling" = "I don't like the way you don't allow me to conduct my affair, unencumbered and without consequences."
