Jealous Friends (not couple stuff lol)

Not sure if this is shoujo but
So like i have (had) a school bff (lets call her Abby) and a tution bff (lets call her Molly) ok and all three of us went to the same college coincidentally.. Abby and Molly only met once at college but didnt talk much.. also i was confused af how to treat both equally cz they're both kinda jealous and possessive lol idk why so i kept both as separate as possible...

Anyway so one day i was with Abby and some other friends, when Molly called me cz we had to discuss something related to some work, so i left Abby and told her id be back in like 10-15 mins... i went to Molly (who was pretty far away like its a long walk) and started chatting and i look to my left and i see Abby fking standing watching from a distance.. i was like wtf and check my watch and its been like 5 mins i was like holy s*** , i was kinda creeped out tbh

Anyway Abby left and i continued talking with Molly for like 20 mins ,then when i went back to Abby and the other friends, i asked one friend "Did Abby get up for something?" ...She tells me "Yeah a few seconds after u left she got up n said she was gonna go see u" ... I was like okaaaaay....

I was like kinda touched ,but more creeped out haha... Do ppl rly do that?
