The only way out is to legally separate from her & move away from her, that is what Arjun should do!
Maya, if she is trying to get violent because of her divorce, then she should be taken to Asylum & treated if possible! Even if she is not curable, she should remain there to prevent further harm to others!
But, if she is really not having any mental illness, then law should do its job!
If Arjun is not taking preventive measures to contain Maya, then he should be arrested first for allowing Maya to have a free run!
But, be assured none of the above will happen a day soon!
Cvs are not done with the show because they are also obsessed to show this repetitive story sequences of bad & mad Maya, pendulum Arjun & foolish Saanjh fighting & struggling only to bore us to death for many more weeks till October!
