We can't make the decision for you. Al-Anon is the solution. It is about you deciding what you want. Do you want to get honest or to continue to live in denial? Do you want to continue to live with a person in active addiction? Al-Anon does not ask you to leave him. It helps you to focus on you and teaches you ways to live with yourself and him.
It is not healthy to live your life through him. We can't put our life on hold for others. We love them, but sometimes we have to use tough love.
