I started Al-anon before I left my ex. I didn't have any DV counselling until after I had left. I have to say that it wasn't until I started that did I feel any true healing. Not to diminish the work of Al-anon at all (it's a wonderful organisation), but coming out of an abusive relationship, be it emotional or physical or financial etc, is a little different. I found in my Al-anon group only one person who had any exposure to abuse per se.
I think it wouldn't do any harm throwing all the tools you can find at the problem and finding a mix that helps you.
