I think most of us grieve.
For me alcohol was one of the longest lasting relationships of my life...and even tho it was a bad relationship for so many of those years, I always hoped it could be bought back to how it used to be, and I missed it like hell when it was done.
Not surprisingly I was like that in other relationships too....
Happily I learned to move on, and I think I gained a helluva lot from doing that
