7 days? 7 days is nothing!!!!
I suspect you're not angry just about the incident 7 days ago, but all the alcoholic behavior attached to that which could have possibly lasted years ( I wouldn't know just based on this one post.)
If he wants you to forget his presumably alcoholic behavior, to me that's like saying "Hey I had an affair! I stopped seeing the person 7 days ago, so everything's OK now. Why are you still angry?"
