DB'ing CAN work. It's the best solution to a tough problem.
DB'ing can continue to work, even after divorce. Consistency and a positive change in you will put a positive change you daughter, and will show STBXW what she's missing out on. You shouldn't do it to 'show her', but to move in a positive direction in your heart, in your mind, and in your soul. Did you do what you could do for your daughter? Sounds like it. My ex-wife is stubborn as a mule as well. Telling her she might be wrong puts her into another orbit. BTW, she's really enjoying her 'freedom', her new married boyfriend, and enjoys being mean to me, as I am still the person that did this all to her. Remember that, msp710 - her anger, resentment, and rebellion can continue, well after D - they are searching for what can make them happy, but they can't make themselves happy, so the search will go on and on. Maybe for the rest of their lives. And that is so terribly sad.
Find joy in every day, in your family, and in simple things in life. God's blessings.
