right love at the wrong time

Finding it so hard to let you go
Realizing after all this time my heart still loves you so
Countless tears for you I have cried
The heart that aches for you knows how I have tried
I've tried to convince myself that you want to be with me
But this love is not strong enough to set you free
I know that you will not leave your wife
One day you will see it's me you want for the rest of your life
I need to be fair to my heart; to let somebody else love me
But how can I when I still believe we were meant to be?
The time has come and we must say goodbye
Goodbye to what we had and just watch it die
I don't have the answer as to why you can't be mine
But this I know is true,
we had the right love at the wrong time.
