Hi mam... I was in a relationship with a boy for 2 years but for those two years he blackmailed me and threatened me and did this even after the break up. He calls my acquaintances almost every day and asks about me. If he finds any information about me, he will continue to blackmail and threaten me. I liked another boy even though I didn't talk to him But I am so afraid that if the blackmailed boy calls him and asks something about me and this boy says something , What will I do then?

Ans: Dear Dipanwita,
And you want to live a life filled with fear? Fear is what makes these boys/men do more of this bullying and blackmailing. Kindly report the matter to your family (with no fear). Yes, they might be upset with you for being in a relationship but surely they will support you to protect you.
If they don't approach a female relative who can guide you to an NGO, who will help you with the police complaint.
Keep a record of all his threatening messages on your phone/email/text chats etc. This can help the police nail him as well. Do not threaten him back but collect enough information as he threatens and blackmails you. It is time to put an end to this. So instead of jumping into another relationship, please end the previous one. And please, give yourself a break to find your happiness within you rather than moving from one to the other. I say this only because one has messed with your mind with fear and this needs to be removed. Be strong and focus on yourself. You owe a peaceful and happy life to yourself!

All the best!
