Can I file a case and get back money

I came in contact with a girl through shaadi.com we spoke for around 7-8 months then we met for the first time after some days she borrowed money she said she is willing to work abroad and she got she took money from me. We met after months I asked to get engaged and go abroad then she didn't go abroad and later she took money from me and later she said My fathers(demise) pension is coming on her name she said wait for some more time we were in relationship for more than 2.5 years and I have spent 7-8L and yes we were in physical relationship too.In this 2-3 years I suspected her many times she was speaking to someone but she said he is just friends she use to lie me and had to go out and one point that guy started torchering me and we had abusive language in exchange.I did forward the audio clips of her to her family members when she denied from unblocking the other guys friends and after even telling her it would our life after marriage Through these time she cheated on me and told me sorry I didn't do it intentionally It all happened bcoz of you never trusted etc.I asked my mother and my mother said if she is feeling sorry she won't do it again if you still love her and still want her I don't have any objection she said now don't give place for more fights get married and stay together whatever I went to her place I spoke about marriage and engagement she said my brother's are saying we can get engaged in month of September or October then I took her to my home I have two sisters both are younger to me she had some misunderstood I talk and play with my sister normally coz I don't be at home on leave I go home for a month in 3-4 days coz of my family issues my sister's ongoing divorce case she went to Mumbai then my fiance started thinking me wrong with other sister also I tried explaining her many a times one day we had small hot talk fighting I tried to make her understand she started tell me that I was having physical relation with both my sisters I slapped her in anger.She ran away after and I went to her place we sorted out with her brother and his friends within a week my father got unwell I took leave in two days my father passed away.
