It is just six months old marriage. There are lot of things to be seen in this marriage in the coming years. It is just a sample of what she is and to what extent she can leap or go.
It is better to remain silent for the present without responding to any of her actions against you and in the police or court you can simply make a firm stand that you're ready to take her back provided she does not threaten suicide.
Dont react to her any type of behavior while she is living with you, if you are not able to tolerate her tortures, you may simply walk out of the situation or place and return after a long time.
You may maintain this silence for another six months period, if the situation does not improve, you may think of dissolving the marriage by a decree of divorce on the grounds of incompatibility and cruelty after completion of one year of your marriage.
She may provoke you to the core by lodging false complaints with police ad before court, you should not be panicked, handle patience which will provide you relief to the prevailing circumstances.
