One thing I always liked about Al-anon is that it is a program where we don't tell anyone what to do. We share our own experience, strength and hope and let others learn from it and make their own decisions based on what works for them.
You gave careful thought to this and made the decision that feels right in your heart. You know more this time around about yourself and how to keep your balance and want to give this another try hoping the relationship can be mended and continue on a good path. I think that's a good thing.
Whatever the future unfolds, I think you made the right decision for you and keep you and your husband in my prayers.
Hugs
