Your life is not a disaster. You're an educated woman with a great career. You are only in your 20's, so there is still so much out there for you to experience. You are out of the denial, you recognize the gravity of your ABF's situation, and have taken solid steps to reclaim your serenity. I do not see "disaster" at all. I see courage.
I hope you find an AlAnon meeting in your area, and try some meetings. You will gain continued clarity and strength from the shared experiences of people in those rooms.
