If a man criticizes you when he has been drinking and then denies he meant it and apologizes profusely and says he does not even remember should you believe it or might this be his true opinion?
Some people can be allergic to alcohol while others can get just plain nasty when they drink. Most people that over-indulge in alcohol are usually pleasant, happy and out-going or simply pass out. Alcohol makes a person uninhibited so you are probably seeing the true side to this person. Anyone who "blacks out" and doesn't remember what they did is a danger. Accept his apology but tell him, "No thanks!"
