They are like those ultra-obsessive-psychotic GF's that will start to hit the gym AFTER the breakup, completely changes, starts sharing her pity "achievements" in public in hope of their ex-BF to see them and in hope of them feeling regret. Keeps lingering in the past forever and doing anything (literally) to fck up their ex-BF's future.
How do we make it clear to these CS frogs to: "Leave us alone, we don't give a f about you and your game"?
