Hi and welcome! There really is no way for you to tell if he is an alcoholic or not. You don't know him that well yet. But, the only thing I can say from my past experience of being in a relationship with an alcoholic, I didnt like his drinking habits when we first met and I ignored them and I am now in the worst situation of my life. I have emotional scars, trust issues and just plain bad memories/experiences from dating him and being drug through his drinking problems. Scars that will probably take a long time to heal. If you are suspicious now, its your choice whether or not you want to explore that path to find out if he truly is an alcoholic. My personal advice is to RUN-especially since you are having doubts this early on into the relationship. You really have no idea how destructive alcoholics can be towards the people in their lives.
