will the real mrs.brown please stand up

i wrote this when i was with my boyfriend and his ex couldnt get a clue...

In Your heart you think he’s yours
But in your mind you know he’s mines
You see it everyday
And hard for you to take it but it’s hard for us to hide
I tired to let him handle it but it seems it won’t go through your head
It’s like you lost in life
It’s like your taking meds
But I’m going to heal your heart and soul
I’m going to let it be known and told
The real Mrs. Brown is here
The real Mrs. Brown has arose
Give him all you want
Give him what you think he need
But at the end of the day
Its not you at all
It’s me
I’m the one he’s with
I’m the one he sees
He spends his time at my home
Sitting right next to me
I’m sorry I had to tell you
I’m sorry you couldn’t get a clue
But the man you once was with
Now is gone
Yes he is through
I’m going to take real good care of him
I promise that’s a fact
Cause now he’s with me
Girl he’s never coming back.
