What a heart wrenching story... as if your broken M isn't enough.
You cannot blame yourself for what happened to D19. And I think it is wonderful that YOU were courageous enough to apologize to her, and then to let the floodgates open and listen, really listen.
When you fought for CAW's kids, you were only trying to do the best for all. Little did you know what would happen.
You did the best you could at the time. Now that you know better, you are trying to do better. That is all anyone could ask. The burden that you have lifted from your daughter is enormous. The fact that you had to do it alone makes it bigger still.
You are a remarkable man. The soul searching you are willing to do, followed by such growth... it is wonderful to see. Your daughter is a lucky woman.
Relax. Appreciate. Be calm. Laugh. Enjoy. Be secure. Be loving. Be loved. Don't personalize. Don't ASSume. Accept. Be grateful.
