Seeing me in him

Last Monday, while checking out what's left on my cobwebbed multiply account, I bumped into an unusual photo in my contacts section; the picture of my "ex" with his new "mate" (which is my actual contact & a friend). My initial reaction? heart rate increased, excessive sweating of palms & the urge to alt-f4 the window. But I was able to survive glancing at the thumbnail for a few seconds and ended up browsing my multiply as if nothing buggled me a few seconds ago. In the picture, I saw them both smiling, lying on bed or somewhere with the "new guy" in my ex's arm. Honestly, really, really, really honestly... to me... it's not a BIG DEAL anymore.
