sorry to hear this, i think it was her decision that maybe pushing her and not any decisions you've made to protect yourself. my famiy cut me off and allowed me to suffer the consequences of my own actions. then and only then could i see for myself how out of control my life had become, then and only then did i become desperate to seek help and commit to maintaining sobriety.
today im a few yrs clean and totally grateful that my family got out of my way and let me fall. keep praying and i'll keep you and your daughter in my prayers
