Searching for parallel dimension Spock/Kirk fic

[lytenakye.livejournal.com]

Hi,
I'm looking for an angsty spirk fic. I've read it a few times but I can't find it again. In it Spock is with Uhura but Jim really loves Spock. They are t'hyla but Spock stays with Uhura. Some how Kirk finds his way to a parallel dimension where their Kirk died at some point, I don't know exactly when though. The parallel Spock immediately wants to claim him.

Kirk is brought back to his original dimension. The parallel Spock follows him and says that they can go back to the parallel dimension and be together. However, they will not be able to come back. Kirk decides to go. Original Spock doesn't want Kirk to go. Instead he wants to keep Kirk as his secret mistress while married to Uhura. Kirk declines and goes back with parallel Spock.
