LOL....
I love your emphasis on father talking to them.
Aik engagement phir bhi aasani se tori jaa sakti hai. Aik shadi ko torna mushkil hai.
Agar tumhay abhi se hi itni takleef ho rahi hai......to baad main kya karo gi?
You want another suggestion different from ending this rishta? Okay here is the suggestion:
Ask YOUR FATHER to talk to him and his Mama about all the problems (where you will live after marriage and their badtameez behavior with you). Your father is older than you. He has experience. Tell your dad to talk to him. Baat karnay k baad, tumharay Father sahi andaza laga sakain gay k ye larka aur us ki Amma kis tarha k log hain. I have told you many times before. ASK YOUR FATHER TO TALK TO THIS GUY AND HIS MOM. ASK YOUR FATHER TO TALK TO THIS GUY AND HIS MOM. ASK YOUR FATHER TO TALK TO THIS GUY AND HIS MOM.
