no, but I was the occasional third with some friends for a while.
That's how he and I discovered out bi sides, because of her dare.
I was thicker and had a bigger head, but he was hair fraction longer.
I know they discussed bringing her gf in, but don't know if she finally agreed.

After a few years, she had a change of mind, but he and I would
still get together occasionally.
Then I guess she put her foot down, because he decided he "wasn't interested", anymore. They were going thru a rough patch, and I know he wasn't telling her stuff like we really were just going out to movies and stuff.
(she had him pretty much whipped, and he acted totally different whenever she wasn't around, more open and such.)
