Looking for a Story: Eames didn't want Arthur then, but realizes his mistake - FOUND!

[_crow_chick_]

I'm looking for a fic that I can't remember the name to about Eames and Arthur sleeping together when Arthur was young and he gets attached, but Eames doesn't feel the same way. When they come together later (on a job, I think?) he realizes Arthur has moved on with an older man. (It's not the one where Arthur marries Julian). Eames eventually realizes his mistake, that Arthur loved him all along.

Thanks for any help!
