Sorry to hear about your situation.
A determination of alcoholism can only be made by an individual. Only an individual can say they find themselves drinking even when they feel they honestly don't want to.
It sounds like you have a real concern/ problem with the drinking and its consequences. Which is understandable, it's hard to believe the consequences would not be present if the drinking continues.
Alcoholism isn't some kind of pass that allows people to force others to put up with unwanted consequences.
