Dear Sir,

Safeguard yourself, your parents and your relatives.
1) Be very polite in all circumstances. Record all conversations (voice, chat, email, letters, etc.) with those threatening and keep the originals in a safe place. Never produce the originals before anyone, not even before your lawyer. You can buy Olympus W-10 voice recorder, which costs about Rs.4500. You can also buy a telephone recorder.
2) Write a complaint to your nearest police station, detailing about blackmailing, her false allegations and her unscrupulous behavior. And request in your complaint to make her stop the threats and abuses immediately. 
3) File RCR (Restitution of Conjugal Rights). Remember to include conditions that she should agree on before she starts living with you again. 
4) Collect evidence to prove that you have neither demanded dowry or have taken it anytime.
5) Collect evidence to prove that she moved out of the bond of marriage for no apparent reason.
6) If she does not already know, make sure that she does not come to know that any of your family members is an NRI. 
7) Don't remain home during weekends and holidays. Have proofs of where you were. For instance, if you were in a mall, have a credit card transaction in that mall and keep the copy of that transaction.

You can consider about continuing this married life amidst such a tremendous pressure and torturous situation.

The purpose of marriage is to live a peaceful and happy life after marriage with the spouse, whereas if she is creating problems every day that too taking advantage of the laws in her favor you may decide about continuing the marriage or not.

If at all she is intending to harass you by making criminal complaint with the police you may first obtain anticipatory bail and then challenge her false case before court in the trial proceedings. 

Don't get frightened by her threats, law is common for all.

If she knows that law is on her side then you should use those laws against her through your mother. 

File Domestic Violence  case through your mother against your wife and a suit of eviction under senior citizen act against both of you on ground of mental and physical harasment.
