"I have it all, I couldn't ask for more"

Its a guy singer, i have a sped up version of this verse and chorus and i would appreciate it if you all could help me find the original song.

(lyrics)

I have it all i couldn't ask for more
Your everything that my heart desires baby
its such a shame
Am i the one ???
cus im still chasin after every other lady
not thinkin bout the one i got at home
and if she leave me then my life cannot go on
shes the sand to my hourglass
the balance to my scale , i cant see her with nobody else
in my heart there i know
its real cant deny
no, no other girl can take her place
but i lie and i cheat i still hurt the one i love
shes all mine no matter what they say
(chorus)x2
im so selfish, so selfish (im so selfish)
im so selfish, so selfish ( it would kill me to see you with somebody else)

bump .... anyone??
