After an ex leaves you, is it possible that they'll make up stories to your face to get you jealous in order to ensure they made the right decision to leave you?

Caught my girlfriend saying she had a boyfriend, posted pictures of only him and I used Reverse Image Search, turned out to be an IG model she got off Instagram from the other side of the world. She's surprised and embarrassed that she got 'catfished' even though she actively got images off his profile

Even with more and more bizarre stories, I've wished her the best and good luck in her school exams and that I'm happy with what we've achieved in our relationship
