is it possible you had expectations tied to those amends to your husband? each of his actions you describe were when you were drinking....and you admit you were out of control. drunk driving, texts to other men (i'm guessing, you said unsavory), and the general "fun n games" of living with a drunk. I guess you could put it in perspective......he could have split.
as it is, you are sober today and he is still there. are the keys to his car REALLY the issue here?
