There are several possibilities. He may be confused about what he wants. He was embarrassed but he knows that you have been a girlfriend. He could be wrestling with a decision and the silence is him working through his misgivings. The other possibility is that he wants to end things. I don't think that is the case because he could just say so. My best guess is that he is working through how to continue this relationship but you embarrassed him in front of his family. He probably has to decide how he will handle that embarrassment with his family and still have you. The big step will be accepting your apology. You are going to spend the next few months getting him to believe it. Being drunk takes someone's confidence that they have in you away. People are very judgmental when it comes to drinking even when they drink themselves. Usually it is because people can justify such a habit in themselves by thinking such things as she drinks more than I do..She has blackouts and I don't. Be patient to see what his opinion is.
