A girl cheated me in the name of love and marriage

Hi, 2 years ago I got a female friend, after almost 6 months she proposed me but I refused because I'm just middle class not well settled and not interested in marriage at that time. I told everything about my position then she said that she doesn't care about my financial position and insisted to love her. As she showed a lot of love, I agreed her after a month After I accepted her love, with in 3 months I introduced her to my parents and told that we are in love and wanted to get marry. They accepted after some discussion, after that she used to come and go to my house and lived like a family member. but she took lot of time to convey the matter to her parents but she gave me the word to marry at any cost. During this period we started living like husband and wife in all ways. Financially and physically. It's almost like living together from last 18 months After Almost 18months finally she told to her parents as I forced for marriage. But they rejected in the name of caste. I tried to convince but they were not ready to listen atleast. But after some days I came to know that she is not ready to marry me. she just asked her parents as I wanted to marry her but she didnot explained about our love and not insisted her parents about our marriage. Because she just did timepass with me and played with my heart. After some days she is getting ready to marry some other guy who is richer than me. I went to her house to speak with her parents then I understood that she don't like me to get marry as I'm not well settled I spent lot's of my money and time on her as we lived like husband and wife. I just stood beside her in every need. But she just did timepass with me for money and sexual needs. Gifts, tours, shopping, small and big daily needs, sex, everything we just lived like husband and wife. Now it's 100% clear that she cheated me Can I take any legal action on her as she cheated in the name of love and trust and made me loss of money and did mental torture by playing double game with me and my family I have proofs of WhatsApp chat since we met for the first time. It contains each and every information what I told above And lots of photos and videos.
