My friend has been orbiting this girl for around 5 years now, and he has known she was riding the CC (she basically flaunted it). Recently they started dating after she cheated on her ex, and he ghosted her. He has a good job, and she is still in school.

Couple Questions:

Should I tell him that he is making a mistake dating a girl with so many red flags?

Why would this girl finally start dating him after him being an orbiter for so long?
