So a month ago everything was fine when my ex broke up with me without any explanation. Everything was fine and normal before that. Then after the call he blocked me from every single platform and blocked all of his friends also and deleted his accounts, all of them.
Now when i mailed him to ask him the reason and told him that i would file acase on him since he called me R word, his uncle has been harassing me and my father.
They are a jaat family from Haryana.
He has also sexually abused me.
What should I do I feel very frightened since his uncle called me 10 times yesterday and harassed me and blackmailed me. I am from India, what should be my next step?
Any advice would be very appreciated.
