How to contact my wife as she has filed police complaint?

I'm a Christian from Goa, and my wife is from Mumbai, we got legally married under the Christian marriage act in Mumbai and in church we got married I'm Goa, now after two years my wife is saying she and her parents are no longer interested in me and wants to get separated from me and proving me that I'm wrong and bad person , I tried to solve the problem by talking to her and her parents but she filed a police case of harassment and threatening against me and police have advised me not to call her or contact her as she is preparing for divorce . In this case how can I contact my wife and make her understand and solve my problem between her as I don't want to go for a divorce .
