The Thing About Love is just 12 shortish chapters and can be found here: http://www.fanfiction.net/s/4175466/1/The_Thing_About_Love It's rated T and described as Hurt/Comfort/Romance.
Here's what the author has to say...
Author's note: This is AU Torchwood because the idea of dead Owen depresses me when there's so much fun to be had with live Owen, especially with his confused relationship with Rory. Basically, I reworked the story that inspired An Excellent Boyfriend into something that I am more comfortable with.
For those who want to read them, the short fic An Excellent Boyfriend can be found near the bottom of the author's ff.net Profile Page here:

Hope everyone enjoys reading!
