Yup, open aa meetings are for anyone with an interest in alcoholism. I hope you find it useful.
I always think the sad thing about alanon is that a lot of drinking is still going on where as in aa mostly it has stopped and living sober is the issue.
In my experience, alcoholism causes us to become emotional cripples. By the time I got sober, I wouldn't have known an honest emotion if I fell over it. If your husband is heading down the same track it may not mean that he doesn't love you, but rather is incapable of expressing how he feels in that regard. The self centeredness of alcoholism doesn't leave much room for loving others, it tends to destroy relationships and most of us drunks seriously regret the hurt we cause. Part of our program of recovery involves making amends for that hurt.
I wish you all the best in the times ahead.
