Felicia, there was a period of time when I went to Al-Anon meetings daily. Every lunch hour, I'd bring my sandwich and sit in those meetings. A lot of times, I didn't share anything, but like you say, the readings and the routine provided me with a sense of... structure, at a time when I felt like the rug had been pulled out from under me and I had nothing to hold on to.
I'm glad you're feeling better. Remember, the way he has treated you says NOTHING about your value and worth as a human being.
