Dear P
I feel very sad about how boys n their parents/ppl behave only because they have a son and play with the lives of many girls. this boy would surely go on a spree troubling inocent girls like you. but you have your whole life ahead. one thing you can do is forget the past and live your life. time will heal the wound. and i pray that god blesses you with the best so you dont look back ever.
another things is teach him a lesson by going to court. but in the bargain you will loose out on your balance life. whic is more precious that the scoundrel.
third things is you approach an ngo, or take actin againt them publicly and they will not be able to get a good (wealthy) girl for their son. this being their main motive. once their behavoiur is well known to everyone on one will want to give theri daughter to such a family. if they get one too they will not be able to get a one as good as you. and you continue to life your life to the fullest.
