I'm so sorry for all you are going through...Please come here for strength; you definitely deserve so much more. As cece said, his conduct when any person who wasn't so stuck in his addiction would be by your side and supporting you seems a sure sign that your choice to leave now and focus on yourself and your healing is a very good one. I believe that our outlook is a huge aid in healing, and right now you need only caring and support and positive in your life.
Keeping you in my prayers. Gentle hugs
