Song starts

"mmmmmm...i see you walk by, from out of my window, i can't believe (that) i am starting to miss you .. and though you treated me bad, i still get this yearning inside...and i still have faith, i still have hope...

Its not too slow or too fast, most likely from the 80s or 90s and is sung by a black male artist who sounds like either luther vandross or teddy pendergrass
