My ex-girlfriend blackmailed me to forget her. There is really no contact. I haven't contacted for two months, and she suddenly sent me a greeting message. What does she mean?

Explain that after the calm precipitation, she still can't let you go, still think that you are her favorite person and regret breaking up at the beginning, so now she actively contacts you to save each other's love. If you still love her and respond positively to her, you will definitely embrace love again and enjoy happiness.
