Gave money to a girl in times of crises now she is not replying

8 month back I gave 3.5 Lakh rupee to a girl in bits and parts. whom I met for a marriage proposal, by my parents however her parents refused and I moved on in my life. After 2 weeks this lady girl approached me through email asking for monitory help and since then she gave me all fake promises that she will convince her parents and took money from me saying that she has to return it to some of her friends as one of her friend took around 4 lakh from her and flew away. I even took loan on my credit card to give her money and now I am paying interst for all this money. She is now not replying. What action can i take?
