I am a Hindu girl I had a relationship with a boy he is Muslim. we loved each other for past 2 years I did lot of things to him that is money and everything, but now a days his behavior seems like changed.. I doubted him and I found a reason too.. yes now I found a reason that I was cheated by him he needs only money and other things from me not my love care and all.. he needs only that from me... If a person did a crime he must be punished that's why i need an advice to punish him and also myself...Please help me to find a solution:-( I am under the problem please help me. He used me for 6 times with full of protection. He promised me to marry me at the right time but now a days he is behaving differently..now my life is in question mark.. My love matter leaked in my family but he gone some where. I have messages and some voice records is this enough to file a case?
