When I was your man - Bruno Mars

Same bed but it feels just a little bit bigger now

Our song on the radio but it don't sound the same

When our friends talk about you, all it does is just tear me down

'Cause my heart breaks a little when I hear your name

It all just sounds like ooh, ooh, ooh, hoo Mm, too young, too dumb to realize 

That I should have bought you flowers And held your hand

Should have gave you all my hours When I had the chance

Take you to every party 'cause all you wanted to do was dance

Now my baby is dancing

But she is dancing with another man

My pride, my ego, my needs, and my selfish ways 

Caused a good strong woman like you to walk out my life 

Now I never, never get to clean up the mess I made, oh 

And that haunts me every time I close my eyes
