Cheated in the name of marriage

Hi I was in relationship with a guy for more than 5 years but it was our secret relationship. A year ago his parents fixed his marriage somewhere else but he said he was not aware of his parents action and he promised to talk to them about us but as time pases the marriage date was near and he did not talk to his parents but kept the physical contact assuring he will talk to them about us and one day he came and to,d he can not marry me as his parents as way excited about the other girl . For more than 2 3 months I was convincing him but I gave up and ended up with sucide attempt. My parents found out about this and spoke to the boy family where they got humiliated and they show my photos where I am chilling with my friends and in office dinner photos etc and claimed that I am character less and can not make me there dither in law . As I was sexually involved with him for 5 years my mom did not gave up and took masjid help as I am Muslim . Now they are humiliating me with those pictures [ decent picture where my female and male friends are there but according to Islam I am not suppose to be in contact with any other men and they are taking advantage of that ‘ those people are just my friends and office mates] Due to masjid pressure they agreed to marry me to there son but asked dowry and still making false allegations and also telling people that i am not a good person I slept with many people I am character less. The sucide I attempted was failed as my parents took me to the hospital and as per the hospital rules the took my statement. It’s been 3 months now I am still getting harassed by there words in front of people. My parents are helpless because I was sexually active and no one will marry me . Also during my relationship period I have given more than 10 lack’s to the guy some by cash some by account transfers. Also if I go legal now does it help me as I tried killing my self 2 months ago n it’s wrong
