By the time my XW expressed that perhaps she regretted her decision, it was too late. Mind you, she didn't tell me directly but let it get to me in a couple of different, not so subtle ways. By then, I saw her as she truly was, and knew in my heart of hearts, that she hadn't really changed and would just do it again.
And not that I need it, but I have the full support of my sons.
Everybody hurts. It's part of life. Don't miss the good stuff.
