My wifes parents wants to remarry her.

Hello all, Mai 2011 se noida me rahkar job kar raha tha or vahi pr meri gf bhi rahti thi, uske parents uski marrige mujhse karna chahte the lekin mere parents ne meri marrige doosri jagah tay kar di is baat ki jab uske parents ko jaankari huyi to wo mujh par apni ladki ke sath mandir me shadi karne ka pressure daalne lage or na karne pr rape case karne ki dhamki dene lage. Mai jis din apni enguagement ke liye ghar aane wala tha us din meri gf mere room pr aayi or kaha ki abhi aarya samaaj mandir me shadi karo nhi to wo khudkushi kar legi or meri building me hangama machane lgi isliye mai kafi darr gya or uski baat maante huve apne 2 frnds or uske parents ke saamne mandir me shadi kar li or ham log husband-wife ki tarah sath-2 rahne lage. Is shadi se pahle meri gf ne apne parents se lakar mujhe 30000rs bhi diye the jo maine unke maangne par louta diye lekin wo log mujhe phir se paise maangne lage to maine unki police complaint kar di jiske baad wo log or mujhse bahut naaraj ho gye or apni ladki ko mere room se apne ghar le gye hain or ham dono ko kisi bhi tarah se ek doosre se pichle 8 monthe se koi contct nhi karne de rahe hain. Agr mai phone krta hu to wo log meri police me complaint kar dete hain or mujhe phone karke darate-dhamkate hai ki yahan se room chodkar chale jao nhi to jaan se maar denge isliye mai last 6 monthe se apne ghar kanpur me hu, recently mujhe pata chala hai ki wo log uski doosri marrige karne ja rahe hain. Meri marriage ki jo 6-7 photos thi wo bhi unhone apni ladki se chupke se album se mangva li. Mere pass sirf mere frnds hi marrige ke witness bache hain, uske kapde mere pass hi rakhe or mere pass is baat ke proof hain ki wo 01-10-2011 se 31-05-2013 tak mere sath wife ki tarah rahi hai. Mai police me complaint karne gya to unhone marrige certificate ki demand ki jo ki mere pass nhi h. Sir kya mujhe koi legally help mil sakti hai jo mai usko apne sath dobara rakh sakoon or uski doosri shadi hone se roka ja sake??
