I was pretty emotionally healthy until I got involved with an alcoholic.Now, my recovery consists of attending Al-Anon meeting at least once a week and working the steps as I choose to work them. I do it for me, because it makes me feel better, and also because it gives me something to relate to with my RAH.
I have also learned through this process how to better handle myself in all facets of life, not just this relationship. Great practical tools for my kit that I can use in any situation. Calm, assertive energy. Acceptance, Awareness, Action. The Serenity Prayer.
Recovery is how ever you choose to make it - and if you don't feel like you need it - then don't. If you find at some point that your life is becoming unmanageable, give it a try.
