That's interesting about sharing personal information with relative strangers. My H is generally a very private person, but during his MLC he shared intimate thoughts and emotions with all sorts of inappropriate confidants. He did this right through into at least the initial stages of reconcilliation. He also found it very difficult to be honest about it, as though the rational part of his mind couldn't countenance what the other half had done.

My impression was that he was so immersed in his own depression and ego-centred viewpoint that he felt it defined him (and therefore was all he had to share with others), and also had lost all sense of how others would react.
