You are absolutely doing the right thing for yourself and your child. I remember my first Al-Anon meeting when others told their stories and what impacted me the most was the women who spoke of how long they stayed with their AH's and how their own children grew up to have addictions of their own - likely as a result of being exposed to an active A. I made the decision right then and there to never again to expose my 2-yr-old to my AH's drinking. Hang in there.
