Alcohol Dependence

You seem to recognize that you are kind of retreating from him and using the alcohol as a pretext to avoid like committing to him. That could have to do with patterns in your past in which alcohol played a huge role in your parents' alcohol addiction but it has more to do with a fear of being intimate with somebody and being vulnerable to them. Maybe you didn't feel safe growing up and with your parents because of their use of alcohol. We all have a right to have whatever it is be our deal breaker in a relationship. Until you have the right to have alcohol consumption be your deal breaker, I don't think he should make a habit of it.
