I can TOTALLY relate. I have felt for awhile that I "can't do anything" without proof of A. I've seen the light, however! If you have read my thread, you'll know what I mean. The behavior is abusive - emotional abandonment if you will. A person doesn't have to be proven to be cheating to be proven an unfit spouse. These behaviors are detrimental not only to the M but to the stability of the family and need to be called out, in my opinion!
I am remaining "friendly" for now - but not friends as such - esp. with this retreat coming up this weekend.
