If I told you how much I think about her

You'd think I was in love

And if you knew how much I looked at her pictures

You would think we're best friends

'Cause I know her star sign I know her blood type

I've seen every movie she's been in

And oh God she's beautiful

And I know you loved her and I know I'm butthurt

But I can't help it no I can't help it

I'm so obsessed with your ex uh- huh

I know she's been asleep on my side

Of your bed and I can feel it

I'm starin' at her like I wanna get hurt

And I remember every detail you have ever

Told me so be careful baby

I'm so obsessed with your ex ah

Yeah I'm so obsessed with your ex ah

La- da- da- da da- da- da

She's got those lips she's got those hips

The life of every **** party

She's talented she's good with kids

She even speaks kindly about me

Ah- ah

And I know you love me and I know it's crazy

But every time you call my name

I think you mistake me for her

You both have moved on you don't even talk

But I can't help it I got issues

I can't help it baby

I'm so obsessed with your ex

I know she's been asleep on my side

Of your bed and I can feel it

I'm starin' at her like I wanna get hurt

And I remember every detail you have

Ever told me so be careful baby

I'm so obsessed with your ex ah

Yeah I'm so obsessed with your ex ah

Is she friends with your friends is she good in bed

Do you think about her no I'm fine it

Doesn't matter tell me

Is she easy- going never controlling

Well- traveled well- read oh God

She makes me so upset

I'm so obsessed with your ex ah

She's been asleep on my side

Of your bed whoa ah

God she makes me so upset

I'm so obsessed with your with your ex
