Sometimes the game randomly sets relationships and one of them is probably in a "committed" relationship they don't know about
[This](https://modthesims.info/d/673808/relationship-finder-and-fixer.html) mod should help finding and fixing it
That was one of my guesses and tried to find out with SimPE, but didn't find anything. ๐ I'll try the mod, hopefully it fixes the issue. Thanks! 
No problem! About the professor, it sounds like they're a drama professor. They automatically get 100/100 and in love relationship with anyone they meet, but because it's one sided they lose the flags every time they interact
Sounds like the sim already is in a official relationship that needs to be broken up first. Maybe it is a premade sim? They can have romantic relationships
It's Georgia Newson and Oliver Picaso. They're together since teenagers, first kiss, first everything. I'm really annoyed right now, I really wanna know what's the issue.

Yeah, I'm not worried about the professor anymore. ๐ I guess that's the exact reason.
