Hi,

It is not necessary for anyone to marry a person who is not compatible for life. So, you have to be bold and tell that person that you would take legal action against him if he is repeating his threat or blackmail against you. In the meantime, you may send informatory application to police regarding his activities. You are free to marry a person of your choice and live a peaceful and happy life.

1. Your marriage is your prerogative. No one can compel you to marry or not marry or marry any particular person. So don't give in to the pressures of your blackmailer or your parents. 
2. File a police complaint against the blackmailer

Yes 

No need to marry.

File Criminal case through local lawyer for harassment.

1) file police complaint against your ex boy friend for stalking under section 354 D of IPC 

2)if he is threatening to post your intimate pictures online file police complaint against him under section 67 of IT act 

Yes you can freely marry another person there is no boundation to marry him. In case he blackmails you file a police complaint against him for intimidation. 

You should approach to Police Department to register the FIR against your Ex-Boyfriend who has been attempted repeatedly to contact you to foster personal interaction despite your clear indication of disinterest and threatening you to expose your pictures and blackmailing to you. As it is an cognizable offence punishable under section 354 D, 506 and 509 of IPC and Section 67 of Information technology Act. 

No there is no compulsion to marry that guy.  You can file a complaint against him for blackmailing and threatening you. 

Nothing as such, his act amounts to stalking and punishable offence for molestation. Complain the police, will issue prohibitory order and repetation will land him in jail.

Havig a relation dose mean you are bound to marry him/her and free to move on as and when like. Non can be forced to act against choice in such matters.

Absolutely, you have full choice of choosing the correct life partner for yourself.

You cannot be coerced by him to marry you. 

Report him to the women helpline cell of Hyderabad Police. Share his phone number, address and other details with Police. Share any evidence with the Police that you have with you demonstrating that he has been consistently harassing you.

1. Mam, please don’t even think that there is a law which says that you will have to marry this kind of a man who not even deserve you and respect you.
2. Its your life, you gotta decide how to live with it. Think twice before taking any foolish step to get married to him.
3. I would advice you the way to deal with it, you should file a police complaint of having an apprehension on this man that he might do something on social media or otherwise to ruin your life. If police doesn’t look into it then please let me know here, would tell you the next step.
4. And please, not being an advocate, but as a man telling you to not to think about this man as someone with a very good heart and etiquettes would be waiting for you.

God Bless You...!

Dear Madam,

First you have to calm and cool. be relax.

you have to sit and think, do u need him?, take your time.

if he loves you truly, he wont do like that

but now he is telling like that denotes he is a psycho

it is a crime too, without one permission , nobody should do like that. it is an illegal also.

if he blackmail again, record it, and complaint to the police station.

1. Make an audio recording while he black mail you and hand it over to the police.

2.Dont try to handle the matter by yourself alone . Talk to your parents or some responsible authority you can trust. It is better to tell your elder brother or parent before everyone around you knows about it.

3.Try consulting SNEHA's PVWC Program or some other organisation.

Having relationship with another person is not a strange thing in Indian atmosphere and it is not mandatory that the live-in partners have to marry each other, there is no provision in law for this set up.

If his tortures are not tolerable, you may issue a legal notice to him warning him from indulging in any such illegal activities including threatening you or else he will face legal actions through court and police.

You can even lodge a criminal complaint with the cyber crime police about his threats to publish the photographs in the internet.
