Fraud and cheated by her girlfriend

I belong to a middle family and my father is a farmer staying in odisha i contacted with a girl who is my school friend and started talking as friend in that time she always told me that i am loving you and in that time againg speakks m just joking after 2 years talking i know that her mother has kidney failure and also her mother is a govt nurse and her father has no relation with them because he was married again and staying with new spouse. Her younger sister was studying and one younger brother who was not getting job. Her land and home was in loan and also there was so difficulties to run a home. Her mother got salary of 1 month in every 3-4 months and their weekly expanses i.e dialysis around 7-8 thousand. In 2013 she knows that i am very much weakness for her and indirectly told me to propose her. From that time we were in continuous touched over phone. In everyday she was calling me and told me to visit her house. When i visited her house i wanted to know her ver critical situation and told me that my home is in loan no others banks are giving loan. If any one will do a 5 lakhs loan then her mother will be taken for treatment at that time her mother cried and told me help me to save our family and get the loan from bank (as i was working in pvt sector. ) i will return money after selling my home. That night girl told me help us and do the loan . I will convience to my uncle, mother about my marriage. After that i assured that i will do loan as this is my 1st love and girl was also beautiful with brahmin caste. That night girl came to me and we were in physical relation. After 15-30 days i got laon from pvt bank of 5 lakh and given to her mother account with RTGS . After some days i feel that she has another relation with other guys such types activities put the mobile in secret mode that no one can see that and with messageing in night to ther numbers. From that i have very depressed and one she told me that i had done sexual relation with other. Even after listening this i cool down my mind and sympathy to my mind that forget all the things as i love her very much. One day i got a message on her mobile that one unknown number messaging that you are only mine. From that from that day i deeply shock her. Afetr 2-3 years relation completed around 9 lakhs i have given to her mother account as well as her own account and also giving loan EMI. Total money will be 15 lakhs. On june 21 at around 12:00 clock i asked her are you loving to anyone? And she was used very abusive word as i messaged all the details what i did for her? I never used any word to her from that night our relationship broken. After 7 days i called to get my money but she told me that i was slept with her and also talked with her she also used abusive word when i asked about to give my money.
