"Second Best"

The Challenge: It's a week before your wedding.
You've just gone back to the neurologist for the results of your MRI and he tells you that you have Multiple Sclerosis.
You go out that night, get blasted, and end up calling your fiancés best friend to help you get home where you tell him the news and end up spending the rest of the night in his arms and his bed.
When you tell your fiancé about the diagnosis he can't handle it, leaves you and his best friend ends up having to give you the bad news that he won't be coming back.
Who's the fiancé, who's the best friend and how does this become resolved?
