It's not 100% your fault it takes two people. Sounds like my wife as well...she has basically cast of our family friends and only interacts with her friends outside of the family. When i look at her and see her act so cold it is so hard to imagine that this is still my wife and this is someone I loved unconditionally. She is like a shadow of her former self.
I agree 150% with Accuracy on the children....I have no idea what the future holds for me and my wife however I will make the most out of this situation for my daughters (8 and 6) so they only see positive interactions between me and my wife.
