Lyrics:

If this is love
Then I will be leaving
Run so fast, run so far
So far from where you are

If this is love
My heart will be bleeding
'Cause bein' loved's like bein' drowned
I get so turned around
It's too much...

How will I know?
How will I see, this feelin' washin' over me?
Like love - the life that steals my sight
I never beg
Don't wanna cry
Spend all my nights just wonderin' why I feel so sure
It's gonna hurt if this is love

So this is us
Not quite like I had in mind
Love is never like the movies
You're not blue, and I'm too moody

If this is love
My eyes will be breathin'
From so much joy, so much pain
Until they seem to say
There'll be change...

How will I know?
How will I see, this feelin' washin' over me?
Like love - the life that steals my sight
I never beg
Don't wanna cry
Spend all my nights just wonderin' why I feel so sure
It's gonna hurt if this is love

Then your smile comes slowly stealin'
Takes me where you are
It lofted like a crash of thunder, that breaks through my heart
I just can't remember what my life was like before
Told me what my heart is for...

How will I know?
How will I see?

How will I know?
How will I see, this feelin' washin' over me?
Like love - the life that steals my sight
I never beg
Don't wanna cry
Spend all my nights just wonderin' why I feel so sure
It's gonna hurt if this is love

If this is love
Then I will be leaving
