Update on the long ex-girlfriend story above:
Guy she's dating calls me on the phone: "Hey, I know this is kind of personal, but when's the last time you guys had sex?"
Me: "I dunno, maybe six months ago. Why?"
Guy: "Oh, she's late and I was just wondering."
And it turns out that she still hasn't started to get over me (after a year) and she's both been keeping him at arm's length and subtly trying to cock-block me with every other girl because she desperately wants me back.
So now that we've got all this in the open and she said she wouldn't do that anymore I told her about all of the girls I'd like to date to get back at her for being a jealous jerk.
Oh, and summer fling girl is doing well. She sends her regards.
