i thnk that's perfect! i figured they went to different colleges too, maybe she even went out of state. andy went to stanford. i'm even open to saying that he cheated on her, maybe even a whole kind of 'on a break' thing but she didn't think they'd actually hook up with anyone else but he did (while exploring his sexuality) and she could have been bitter about it if you wanted but eventually after they were both back in san fran, they kind of wound up resuming their old relationship minus the romance?
you'd get several lines by proxy too: ~maxll is a childhood friend, ~clif a high school friend, and ~dakotac has been friendly since about high school age but she's a lot younger so they weren't really close until probably after college.
