He is always telling me to come to him but whenever i try to convincey parents , they just hate that guy and really i also feel sympathy because he were always there to help me but i don't have feelings any more , i am unable to ho him away because of his blackmail but i am unable to stay with him because i don't want to and so much confused what should I do . My parents are searching boy for me buty mind is like should i play with his life because he won't marry ever , i m facing guilt in my life.
