Nothing wrong with being That Guy, I'd love something like that! If he wouldn't have minded being with a girl who could probably break his neck, she certainly wouldn't have minded being with someone smarter than her as long as he didn't treat her like she was stupid. Amicable split seem OK? Now that she's on the app, they can compare dragon tattoos... and actually, that could even be a way for them to reconnect, maybe, surprise her lease is up and she's checking out the market?
