My XW was hurting so much that it was the only alternative, the only action she saw. Doesn't mean that I did, will, or can understand. Actually, to some degree I do now.
XW was hurting before, and she's hurting now, maybe worse. And when I hate her a little for "what she did" to me and the kids, I don't have that feeling when I try to understand her perspective; I feel extreme sorrow. Because I do love her, and it kills me how she's felt.
