Soccerdad...not sure how long you both have been working on changing the relationship...but it takes a while to change behavior.

If you were seeing a counselor together & you all expressed what happened with "the walk" that counselor may have said to your wife...he cannot read your mind - I believe she is as frustrated as you are and her reactions have to do with fear.

If you are done..ok...but do not keep score of how many times she is going to act in ways that you cannot tolerate. Resentment is so built up...IMO you guys cannot do this by yourselves - there is a reason she is acting like she is...is it worth figuring that out...with the help of a professional????...If she does not want to get help....
then make a decision. But even if you do get help...it's going to take awhile to change things.
