Identify this please

I was out in a club when this rnb tune came on.
the only lyrics i remember are...
Chorus - ''I dont wanna be all by myself''.....
''I dont want nobody else''.

at the end of the song it says

''i can(t) be happy without you'' , repeated 4 times

someone please help me out, the singer was male and had quite a high-ish voice

hmmm, can this be

Brian Mcknight - Happy without you ??
