Hi
You should proceed with divorce on of the grounds prescribed under law, cruelty, desertion or adultery based on the facts of your case.
If you feel you can't live with your wife initiate a divorce proceedings.
Consult a lawyer in person with detailed facts, incidents and events which troubled you to think about a divorce
Regarding 498A, approach a court with anticipatory bail if an NC lodged by your wife or an FIR filled and the cops call you to appear before them.
By existing provisions the police h has to give you a notice, once you get a call or notice to appear before the police go to court and move anticipatory bail. Otherwise session court will ask you to approach when any police report of an offence, a complaint by your wife.
Apprehension of arrest is a reason to file anticipatory bail, but in martial dispute every moment is an apprehension, so unless there is a complaint and police give a report to court, your application will not be allowed.
