My Boyfriend's Ex Girlfriend

My Boyfriend's Ex Girlfriend
One day, I was sitting in class
''Gotta know'', they'd said
'Watch your back'
Someone told me who it was from
She wasn't happy 'cause she just got dumped
It was over, but not in her mind
It's not my fault he left her behind
I always knew they had a history
I didn't know that it included me

She wasn't ready to let him go
Now I'm dealing with a psycho
My boyfriend's
Ex-Girlfriend
I think she's going off the deep end
She loves him
She hates me
They broke up
Now she wants to blame me
Na, na, na, na, na
Na, na, na, na, na
Went to a party on a Saturday night
I wasn't planning to getting a bite
All I wanted was to have some fun
You know I never wanna hurt no one
She walked over, thinking she was so tough
She stood me down, but she had to look up
Then she started to lose control
What can I say?
That's rock and roll
I wasn't sure, but now I know
That I'm dealing with a psycho
My boyfriend's
Ex-Girlfriend
I think she's going off the deep end
She loves him
She hates me
They broke up
Now she wants to blame me

Wake up girl, 'cause it's over
It's time to get a life (get a life)
Go cry over your own shoulder
Hey you, see now he's mine
My boyfriend's
Ex-Girlfriend
I think she's going off the deep end
She loves him
She hates me
They broke up
Now she wants to blame me
