That I forgave until I lost myself, that I communicated but wasn't heard. That really, most of the time I gave it all I had but it takes two. And two of us just weren't doing it. And I can live with that answer.
Another piece of the puzzle, well done! Self-awareness! Also vital for the Going Beyond of resentment. You have to know things about yourself.
That, cf @Greek, is one of the things I was missing when I "wasn't" SP but was SP-with-WAW.
The irony is that I always had that self-awareness, but it seemed I was letting myself off the hook too easily. But I've had 18 months of painful and intense reflection trying to find "where I went wrong" and--aside from becoming someone I wasn't in trying to be "good enough" and still falling way short, in xH's eyes, at least once Something Better came along--I truly don't know what I'd do significantly differently. Which until very recently has been Too Simple--but maybe perhaps Too Simple is good enough.
