Time-Wasting

I have started writing my yuletide fic, and it's not even December yet. Obviously I would like to procrastinate on this, and I have already ironed everything in the house that can't run away or bite me, so a meme which I have cheerfully swiped from woldy: The fannish breakup exercise.

Give me a pairing, and I'll tell you something about the reasons, circumstances, or consequences of their breakup.

Answers will be a few sentences, usual fandoms apply.
