I went to Alanon weekly for 5 years before I filed for my divorce. It was the only thing that kept me sane!
For the last two years, my attendance decreased, partly due to work schedules, being a new single parent, and I didn't feel as much need. Honestly, something else too... I'd had my fill of talk of misery, and needed to get with other healthy people again. Since my separation, I have pushed myself to get involved in new community groups, and outings to things I've never before attended. It's another way to leave the past in the past.
Now, when I need some understanding as it relates to my X when the topic surfaces, I come here!
