Hello Dragonfly,
Welcome to SR....
I'm glad you found us and are bettering yourself by attending Al-anon meetings and counseling...
I wish I had the answer regarding your question about interventions...
You are correct, that unless the individual wants to change on their own, it's very difficult to convince them otherwise...
As I'm reflecting on your post, I'm thinking that you could try an intervention with a trained professional, but in order to keep your co-dependent side "in-check" I would strongly suggest trying to let go of any particular outcome...
This way you are still helping (but not doing so at your expense...)
After saying what you have to say, the only thing you can do after that is say no more as the rest is up to him...
Although my relationship with my boyfriend ended because of his refusal to accept help, I will never regret taking a stand for him by expressing my concerns about his well-being...
Your post has me wondering if any of the participants who are recovering from Alcoholism have done so due to an intervention?
I'm sure others will respond with some more feedback...
I wish you the very best....
Linda
