Do you know who sang this song or the singer's name?

(Black-American Female singer):

It’s the things you say
It’s the things you do
‘Cause you never know who is watching you.

Better think about all the good & bad things
in a love affair
You might look around & find out
I just won’t be there.

Oh, you better hold on
‘Cause if you ever let go
I might be gone.

You know there’s always someone
waiting to take your place
Honey, use your mind
I got the lover you’ll never find.
