My girlfriend tested me with a fake profile. What do you suggest I do?

My girlfriend, who's always been a bit cynical, decided to test me with a fake profile. She created a fake social media account and started flirting with me. I played along, thinking it was just harmless fun. After a few days, she revealed it was her all along, saying I "failed" her trust test. I felt completely betrayed and broke up with her on the spot. Now she's bombarding me with calls and texts, saying it was just a joke and asking to get back together. Should I even consider taking her back after this?
