Help Me Out!

I heard this song while I ws waiting for my bus the other day but they never said the name.

I know it from what back ,wondering if anyone knows what it is.

Lyrics go something like:

"I've heard it all before...I'm showing you the door...oh darling I dont miss you anymore"

It is sung by a woman and I believe that it is from the late 90's but dont hold me to it, I could be wrong.

Thanks
