ndark, I am very curious as to why spouses leave "just because they're unhappy....." It just seems so vague and frivolous. And so very destructive. Do they not take the time to look at the big picture?
I am not judging you in any way, but I am seriously wondering what it would take for me to trust a man who walked out on me, and I am at a loss. How would you feel if your W did what you did? It's the lack of empathy that has me so completely stumped in these situations.
It would never, ever occur to me to just up and leave someone who loves and trusts me.
