I read your poem and it was so sad and beautiful too (though you didn't likely see the beauty in your own words).....I think anyone would agree.
You're very young and nobody has told you about this kind of sadness that you're feeling. You hurt so much inside about it and feel less because he has chosen another girl over you.
Its not your fault...you only loved and trusted...and that's what love is.
Love is taking that risk for someone and its a reflection of the goodness and hope in your heart.

Once your tears are cried, wipe your eyes and remember these things you have:

You're a beautifu young woman
you have love in you
A full life ahead of you and many happy days to come
You know more about love and how it's fragile
It's a blessing that this man is not the one and it is your fate
Be Picky....choose a man with a good heart....and a heart for you
Don't do anything else differently...love with all your heart....risk it hurting agian.
You know if you love someone you would give them the coat off your back to keep them comfortable and warm
Be happy...the world will get sunny agian for you
Dream....keep your dreams of a happy love
One day you will be thankful it all worked out just the way it did

thank you for the advice..its true that i am really hurt
but i now (just like what you said) i can get over it...
ill be able to look and think what we had in the past without
me crying...
again thank you
