From the AA Big Book
Resentment is the number one offender. It destroys more alcoholics than anything else. ...p64
....resentment is infinitely grave. We found that it is fatal. ...p66
We look at all our resentments in AA and work the steps to remove the past ones, and ones on a daily basis. We understand they could kill us if left to replay over and over in our heads. The fact that you have been bothered by this for this past week, tells me that you are just like any one of us alcoholics as far as resentments are concerned.
I think it is a good idea that you see that these people are not the people you need to be spending time around. For those you really care about you can create new social occassions not surrounding alcohol. You could be their coffee or lunch partner, rather than drinking partner.
Finally, I think it would be wise of you to look at your part in this. You are an alcoholic and you were encouraging a drinker (who you have already said has a problem) to drink more alcohol. Now why would you do that, even if it was a joke?
