Reminds me of "Take my Breath Away" by Berlin (with covers by Jessica Simpson and others)
Watching in slow motion
As you turn my way and say
Take my breath away
Take my breath away
However, the lyrics to Emma Bunton's song, "Take my Breath Away", maybe a better fit for the song you are looking for.
Every waking day you take my breath away
With every word you say you take my breath away
You look at me that way, baby come what may
Another candidate is the old Burt Bacharach/Hal David song, "The Look of Love" which has been recorded by numerous artists including Diana Krall, Sergio Mendes (featuring Fergie), Nina Simone, Anita Baker, Issac Hayes, The Zombies, etc.
The look of love is in your eyes
a look your smile can't disguise
the look of love
is saying so much more than just words could ever say
and what my heart has heard, well it takes my breath away
Them that can, do; them that can't... memorize Artist and Title
