Story Writing

Sads,
The concept that i am thinking of involves 3 teenage girls (of course!) and the way their life changes over the years.....Inital chapter has some introduction to these characters ...

1. One girl goes abroad to study meets a young man and  falls in love. But fate takes her back home to take care of her ill father. She never marries and through letter knows the progress of her lovers life. Though many men fall in love with her, She refuses to part with her memories of the past.
2. Another one moves to europe (to study or work not decided), falls in love with a girl. Marries a guy following parental pressure. Goes back, mental conflict. Divorces. Comes back as the other girl refuses to be a part of her for life. Meets a young man, who has his own reasons not to marry and finally settles down with him for the society.
3. The last one moves to middle east and am not sure of an exiciting story to pull through
Ending:Something feel good...:-)

Love
