लिव-इन रिलेशनशिप को कैसे सुरक्षित रखें और दोनों की सुरक्षा कैसे सुनिश्

Sir, meri age 18+ hai aur ladki ki bhi 18+ hai. Hum dono shaadi karna chahte hain, par abhi meri shaadi ki age nahi hai aur ladki ke ghar wale usko maarte hain aur mujhe dhamki dete hain ki agar ladki mere paas gayi, toh mujhe jhoothe cases mein fasa denge. Ladki ko petrol se jalne ki dhamki di ja rahi hai. Sir, agar hum live-in relationship agreement banate hain, toh kya police humein pareshan karegi? Mujhe protection kaise milega? Main ladki ko apne saath lana chahta hoon, par usko vaha bohot problem ho rahi hai. Sir, please help kijiye.
