It must have been difficult to finally make the decision to move on. My mother stay with my abusive father for 40+ years before she left. She moved out but stayed in a relationship with him. She said was easy because she would leave from visiting him if he starting drinking, and because he wanted her to stay he waited till she left to drink.
Not saying this is for you. It looks like you are on the right track. When you leave you know you can rebuild your life and start over.
