ABCs of Exes

I used to think that I was unique in my inability to get over significant ex's. I've since come to the realization that othe people are just better at hiding it.
Now, I don't mean that initial recovery period where every person, place, and thing sends you into emotional turmoil. I'm talking down the road when 95% of the time that person doesn't enter your head. Then, all of a sudden something reminds you of them and all those emotions come running back.
This something can be running into them, their birthday, a rediscovery of a gift they gave you, stumbling upon the place you called your own.
Or inadvertently learning that they are in a new relationship, which is what happened to me.
Well, inadvertent is a stretch...I was stalking him on Friendster (don't pretend you don't do this) and saw he had updated his profile. I was expecting something simple like a new favorite book or song (replacing ours perhaps) but no..."In a Relationship."
Why do I care...It's been a year and a half since we broke up. Well, in fairness, less than a year since we stopped sleeping together for good but still. I'm with someone else who I fully acknowledge is both better on paper and a better match for me. But still this news sent me into a day long panic session over im and email with friends who know him, and the suspected new gf (i'm much cuter by the way.)
But I'm over it...I guess it's true that revenge is the best medicine. Now if only he obsessively checked my profile and could react to my new dating status.
