@revathilogan,
Dear Revathi,
I feel very sad for the present situation you are in. Dear, please remember few points when you start liking a guy -
1. Most of the boys in the world look for opportunity to have some good time (you understand what this is) with majority woman.
2. I hope that you had not gone to an extent of being Physical with this guy.
My sincere advise to you - Please do not talk to him any more. He is just your friend/bf and nothing more. He is not your husband that you keep worrying about him that much !
Start living your life normally, concentrate on something worthy like studies, job etc., and I am sure you will surely come out of this.
Marry soon a wonderful guy whom your parents choose and start leading a happy life.
Trust me...you will be very happy in future. I know now, it is hard...but believe.
