I think there's no need to go after her.
Just leave her alone man.
She don't want to talk to u so just move on.
I don't understand why is it so difficult to accept a reality that she is not interested.
And changing ur way of living for some other person is not the solution at all.
Coz if after that she comes to u then that wud be just because of ur artificiality.
Just be urself and don't change urself for any other person.
One should never make any person soooo important in his or her life that he or she loses his or her individuality.
Live life king size the way u want to.
And remember, MAINTAIN UR INDIVIDUALITY.

I M totaly dis-agree with Anwar khan, u can attract a girl by ur look or out-look but cant maintained for a long time it is ur manner and quality/qualification which describe urself.

One morething that friendship and love never geterate forcefully/intentionally. If she is not interested with u then leave it yaar, i know it is not easy but also not impossible too.

Secondally u hv not mentioned that what u r doing, i.e. study or job. diveret ur feelings into creativity and work hard on study or job.

Last thing i want to add is it is not ur love or friendship but it is ur EGO which hurt, so be mature friend. Life is not all about Love or Friendship with sanjana(raina) only. We all r ur friends.

All the Best.
