Wow.. since reading those last comments of yours, Toots and Claire, I'm sort of reeling with the import of that implication-- that I'm essentially wasting my time trying to figure out how to deal with the feelings lingering from her. She's out of my life: no kids, no contact, no property. The only effect she has on me is the one that I invent in my own mind.
And in that regard, the only effect that matters is that she left me alone, because that's the only effect that appears externally, in that I look around and there's no one there. The other effects-- her hurtful behavior, and the desire I have for her to show remorse-- aren't there unless I create them.
