Here they say when a person becomes an alcoholic, he or she stays the same age in terms of maturity.
I am sorry you are walking on eggshells, around his alcoholism... "what kind of relationship is that?" my answer would have been "a relationship between the master alcohol and its puppet!!" (sorry, my anger speaking..)
The thing is not if he minimizes or not (that is what alcoholics do) ... the thing is.. what do YOU want? what do YOU need? as GiveLove says... "is this what you imagined as a little girl?" that is what is important...
I am sorry he is still drinking... he does not seem anywhere near recovery. Remember he may never change , but you can.
