Brian was no longer willing to take that kind of risk. He had responsibilities now, to himself, to Gus, and to Justin. Brian didn't know if he was more upset about losing his dream of New York or realizing he was no longer the person who would give up anything to make it happen. Either way, Justin coming back to Pittsburgh was salt in the wound.
This part really got to me. Poor Brian has grown up, and even though he accepts it, he doesn't necessarily like it. I'm glad it didn't cause a rift between Brian and Justin.
Loved this story. The rings were a pleasant surprise. Brian briefly thinking about going raw in the future was a nice touch. I can see it happening this way. Very well done.
