Thank you for your perspective. The answers can never be found because so many adjustment and rationalizations skew them. After the past four months, I no longer know what is or isn't. It's all been scrambled by emotion.
When I do talk to meaningful friends, I know the depth of love I feel/felt for him, just abhor the guy he is now. Instead of getting so furious about the excuses he gives to the kids, I realize I allowed those excuses in our marriage. Silly.
I'll just do work in the present. What will happen, will.
