[fic search] (sort of) cheating!Harry

[silverkagaya.livejournal.com]

Hi, I'm having trouble remembering this fic that has been gnawing at the back of my head all day. It is H/D, with established relationship. I'm most certain they have children together. The main theme is that Harry somehow 'cheated' on Draco, I think Harry had a co-worker who was pursuing him despite knowing that he was married. If I'm correct they kissed at one point, Harry didn't want to cheat on Draco but he didn't actually stop the kiss either, but then he felt awfully guilty about it. He told Draco at some point and Draco was very mad, and there might have been threats of divorce. It was a happy-ending story, however.
Does it ring a bell to anyone?
