Would an ex “pity” like a selfie?

This guy I dated who ended things with me liked my Instagram post the other day... I’m pretty sure he left me because he wasn’t fully over his ex, but continually hits me up with a “Miss you” text. So IDFK lol.

He’s really sociable, likes to party and has a lot of friends. I was quite the opposite so I’m not sure if he feels bad or is trying to keep his tabs?
