Assalaam alaikum brothers n sisters...

I have a question about my parents...
My parents were suffering from financial constraints during 1998 -1999 so they took some assistance from a non- muslim.. Few days later that non-muslim started behaving bad with me...he proposed me and followed me to my school n later on to college...I complained about it to my mother first..she begged me to tolerate it bcoz they are under his favour... the same thing later on I complained it to my father he said he cannot go against that non- Muslim because he is indebted by him during hard times.. Till date my parents entertain him for lunch or timepass.. I m scattered n burdened by this day by day...Whenever that non-muslim followed me I took help from my male colleagues and landed up in huge problems.. can any1 help me overcome with this..
