Lyrics:

If I had only known our love would end this way
If I had only known that there would come a day
You'd break each vow and leave me all alone
But it wouldn't be so bad if I had only known
If I had only known how many tears I'll cry
If I had only known that lips like yours could lie
A love that was once mine now is gone
But I might have been prepared If I had only known
I could have told myself 'Get ready, cause your heart is gonna break'
I could have said, 'Let's see just how much pain that heart of yours can take'
But there's no way to know just what tomorrow brings
And there's no way to know when clouds will bring rain
Sometimes the sun in heaven shines so bright
And then without a warning hides its face from some
If I had only known our love would end this way
If I had only known that there would come a day
You'd break each vow and leave me all alone
It wouldn't be so bad if I had only known
