Girl Falsely Accused me of Breach of promise to marry after Sexual Relationship

Hello, Here are full details of this case. I live in Bangalore & that girl lives in Delhi. She had send me a message on my Facebook profile after going through my Shaadi.com profile. I replied back & we began chatting. As I've created the profile on shaadi.com for marriage purpose,I asked her what she thinks about our future. She agreed and after that,we were in a couple relationship. After few days I told my parents about her & she also informed her family about me. Both of our parents agreed & took a step forward to meet. Meanwhile,we (me & that girl) decided to meet. On July 2017 she came to Bangalore & stayed at my apartment for about 5-7 days. After 1 month,I traveled to Delhi to meet her. We Both checked in a good hotel,submitted our Photo Id at the time of check-in. On October,she again came to Bangalore to celebrate my birthday. In all these 3 situations,I never had intercourse with her,means she's still a virgin. On December 2017,She got to know that I was in contact with my previous girlfriend & had a sexual relationship while being in a relationship with her. I've tried to convince her that we're no longer in a relationship. My previous girlfriend also called her. But she's a bit physo, she called my parents (they live in Bhopal) & misbehaved with them. After 10-15 days, she came back & apologized for what she's has done & asked me to continue the relationship. I told her as you misbehaved with my parents,they will no longer accept you. She send me some 4-5 messages to continue the relationship,she also send me her debit card details to book her flight tickets to Bangalore,so that she can stay at my apartment for 3 days. I didn't wanted her to visit my apartment again. I told that flight tickets are too costly for the selected dates. Later on, when she realized that I & my family will never accept her she started sending abusive messages to my ex-girlfriend. To avoid further messages, my ex gf messaged her back, if she continues sending abusive messages she will forward the pics of her and me to her dad. She did this only to scare her. She has no photo of ours. We've also talked to her dad so that they will help us but he started supporting his daughter. On February, at month end, I received a call from sub-inspector (from Delhi) that this girl is filling a complaint against me. Charges he mentioned that I've made fake marriage promises & had a sexual relationship with her & a Rape charge. He told me yesterday (07 Mar 2018) that he is sending me a notice via speed post. In that notice, there is date mentioned & I've to visit police station on that date & convince that girl to not to proceed to file the case. The main point is that its nearly impossible for me to visit Delhi due to heavy workload. I have all the chats & recordings where it's clear that she is virgin & all was done with mutual consent Any suggestions what can I do to resolve this matter?
