That my ex (of less than two months), who "still cares a lot about" me and who I'm still "good friends" with, is now in a relationship.
Have some fucking respect.
(Or at least LIST WHO IT'S WITH. Goddamn.)
Edit: Asked him about it. To his benefit, it's not the person I was always afraid he would break up with me for... it was my second guess. And they're going to be in it for the long haul.
Second time now that a relationship of mine has ended only for the other person to move on pretty damn quickly to The One.
