These lyrics really describe my feelings at the moment I guess:
"I know you think that I shouldn't still love you,
Or tell you that.
But if I didn't say it, well I'd still have felt it
where's the sense in that?"
And then I think, C'est la vie, Such is life... And I know one day we will meet again, he will be married and I will cry. That is the day I will die inside. And I'll meet someone like him, and I will be born again.
Alas, love, what a silly emotion it is indeed; when you feel the loss of something that you never had, that to me, is the cruelty of love; every rose has its thorns...
The song is by Dido, it's called "White Flag", and there is another which also describes the joy he brought to me; "Thank You".
