Oh my god you're so so pretty
I see everything that he saw when he first saw you
And I don't want to admit it
In some alternate universe we might be kind of close
It don't throw me off, seeing you out, seeing you around
Mostly I don't think about it
It's only weird when you call him
It's only weird because we're not friends
Are you hoping he'll catch feelings for you again?
So insane to think that now I'll have to pretend
That you never even happened
Oh no no I don't think I can
No no I don't want you to see that I forget who I am
Yeah I know I wouldn't want me to be my ex boyfriend's new girlfriend
Girlfriend, girlfriend
So, sorry I'm your ex's girlfriend
And I'm catching myself thinking about all of the ways that I could lose him
And I can't help being a mess cause he's the one that's gotta choose it
He is showing up, always puts me first
Not to f*ck you up, but we're so in love
You make it weird when you call him
You make it weird because we're not friends
Are you hoping he'll catch feelings for you again?
So insane to think that now I'll have to pretend
That you never even happened
Oh no no i don't think I can
No no I don't want you to see that I forget who I am
Yeah I know I wouldn't want me to be my ex boyfriend's new girlfriend
Girlfriend, girlfriend
So, sorry I'm your ex's girlfriend
I wanna know exactly what the two of you had
Then I take it back, yeah I take it back
I wanna know if he still thinks of you like that
But then I take it back, yeah I take it back
Cause it's only weird when you call him
Yeah it's only weird when you call him
So, sorry I'm your ex's girlfriend
