Lyrics: David Guetta/Franklin/George Robert Merrill/John Newman/Narada Michael Walden/Ollie Green/Peter Dalton/Shannon Alexandria Rubicam
Lookin' back lookin back' at the past
And what we had wooh-oh
And I hate the fact
We can't turn back
It's what I did to hurt you back oh
And I know that I did you wrong
Know that I let you won
Know that I did you wrong
But I was running blind
And I wish I took the time
To really ask you what you feel
So tell me now
How will I know if you really love me
I say you pray with every heartbeat
I fall in love whenver we meet
How will I know
How will I know
Ooh-oh-oh
How will I know
Ooh-oh-oh
How will I know
Ooh-oh-oh
How will I know
Ooh-oh-oh
How will I know
Every night I'm running wild to heal the scars
And clear my mind oh yeah
But it's hard to find the space
I need to contemplate
That your not mine anymore
And I know that I did you wrong
Know that I let you won
Know that I did you wrong
Did you wrong did you wrong
But I was running blind
And I wish I took the time
To really ask you what you feel
So tell me now
How will I know if you really love me
I say you pray with every heartbeat
I fall in love whenever we meet
How will I know
How will I know
How will I know
Ooh-oh-oh
How will I know
Ooh-oh-oh
How will I know
Ooh-oh-oh
How will I know
Ooh-oh-oh
How will I know
Can you tell me
I need to know I need to know
How will I know if you really love me
How will I know
How will I know
How will I know if you really love me
I say you pray with every heartbeat
I fall in love whenever we meet
How will I know
How will I know
How will I know
How will I know if you really love me
I say you pray with every heartbeat
I fall in love whenever we meet
How will I know
How will I know
How will I know
