Do I have low self-esteem, or am I just being hurt by a disrespectful partner?

My husband is usually a very kind, attentive, and compionate person. But something happens when he drinks. I feel like saying, "Who are you, and what have you done with my husband?" I feel that he says very inappropriate things to and in front of other women, both friends and strangers. I have tried to explain to him that this hurts me. I am an attractive women, I work out, eat healthy, and try to take care of myself. So I am not bad looking. He tells me all the time how good looking I am. Then he turns around and says things that embarr me in front of others. I basically feel that it is just so disrespectful to me. But then I have heard others say that I suffer from low self-esteem. You know, I usually feel pretty good about myself. But I know that is not all there is when it comes to self-esteem. He just turns into someone that I don't know. Talking to him lately, doesn't seem to get through. I have been hinting lately that some people just hear your words, not listen to you.
