what would you do in this situation?

okay so i broke up with my ex 2 months ago (but he was trying to get back with me like 2 weeks ago) and after doing some petty stalking (lmfao) i found out he’s courting a girl that lives nearby.

today, while i was on the bus, there were two females who kept glancing at me and talking. i recognized them as the new gf’s mother and best friend. i feel like they recognized me too and idk lmfao

if you were me, what would you do the next time you see them? what would you do when you see the new gf?
