Kirk/McCoy fic

[hromo1956.livejournal.com]

I only have a small scene from the fic but I am hoping someone can help. It is near the end of the missions and Kirk emails Bones about not having his papers to re-up and Bones attaches a job offer on earth and sends it back. Kirk replies saying good luck and that the stars won't be the same without him. I think they are in a relationship but not getting along and this is Bones way of breaking up?
