The best expectations with an alcoholic are no expectations. We are surrounded by these images on the TV screen and in movies about how things always end up perfectly balanced - there is some sort of closure and everyone goes on their merry way. The closure you're going to get from this is likely going to be what you make for yourself. Hanging around and waiting for anything from him is going to breed more resentment, as expectations are wont to do.
The bigger part of this is realizing (and accepting) that none of this has anything to do with you. He is an alcoholic. He is doing what alcoholics do. His actions don't have anything to do with you, it's all about protecting the addiction. Addicts don't do things TO people. He didn't do any of this because of anything you did or didn't do or say. It's not about you. To him, people are expendable and there will always be another enabler to suck into the vortex. All of this just to be able to drink. Be glad he's gone and not talking to you. He did you a huge favor by cutting off contact.
