Yes, really! You have every reason to be in Al-anon given what you described. If you took away your own problems with alcohol, you are still left with a guy with issues of his own. Step over to the friends and family forum and see what people have to say.
And I hope you will take back your right to a fair discussion. You may not be perfect, but your past mistakes don't mean that you don't have a right to a balanced relationship. Silencing yourself in the face of unfairness isn't the answer. The survival of your marriage depends upon you finding your voice.
