Hi
Since you have no children it is better to take divorce by settling the disputes amicably.
If your wife is adamant in troubling you the option is to initiate procedure from your side.
You can file a divorce on ground of cruelty after one year of your marriage. You said your marriage is one year over,so you should file and independent petition against her in the Court.
Once the she receives summons from court she will have to come to court
Do not agree for any sorts of extortion and be steady with your divorce.
There will chance of compromise nd mediation in the court ,then insist for a mutual consent divorce and end if she too agree there you can be free of the marriage.
Surely she will ask for claims of maintenance or alimony which you should anticipate
Maintenance and alimony is decided on the. Base of your in come which also by considering her ability to earn .
Don't live by bowing your head in marriage under pressure and then compromise, it is advisable to fight it out and get your right to live peacefully.
