By showing illeegal proofs, person claims that i got married with him.

Hi I just need some suggestion, one of my beside neighbour is showing proof that I got married to him in Arya Samaj. He is also having the Arya Samaj married certificate, registration form (pre-condition form for Arya Samaj marriage ie 15 days prior). I believe that after the Arya Samaj marriage, the couple must register in the Registration Office which is not done. But practically on that day, I am in the office where the video footage of the company expired for that day. After this instance, I complained to the police and the SHE team but they are saying that marriage certificate is the Legal proof of document which he as submitted. And the police is also saying that all the Proofs are correct though the proofs (like photos and videos) are morphed.they are not even sending them to the forensic lab and also saying that marriage certificate is only final proof without interrogating the case. And finally, the guy is asking me for divorce. But my conversation is that, I didn't get married how can I give the divorce to him. and also he filed cases on me(Human Rights, cheating, District Court and high court.) I believe is that if he is really concerned about me, he would have not filed a case against me and ask me for divorce. How can I resolve this case. Please suggest me how can I proceed further legally.
