Wow! You have made such progress...I'm so proud of your whole family!
I showed your daughter's letter to my son and he has it on his desk to refer to at times when he is feeling sad about his father.
My husband was remorseful at first, but has gradually drifted back to his behavior (in a modified fashion). I am getting my nerve up to see a lawyer, and your healthy resolve has given me the courage to do it!
Keep your positive family experience going...you are my inspiration right now!
