Ditto, here.
Short version: Friends don't leave!

Long version: If any friend demonstrated - proved - to me that his/her word, promise, commitment (let alone vow) was meaningless - worthless - that would be proof-positive that he/she ended our friendship at that point.

"Friendy"? Yes
"Civil" (even tho I hate that word)? Yes.
Friend? Afraid not. Too late.

With fruit, with weeds even; but gather them
In the one garden you may call your own."
