I put on mascara 'Cause it's not gonna run tonight Put myself back together Picked out a dress and poured a glass of wine My girl's picked a place, that's just not your style Like there's gotta be miles between us Like getting out might get you out of my mind I just can't believe I'm the ex-girlfriend Not even your friend You were my ride home Bet you're driving some new girl around I used to be everything Now I'm nothing that you've got to worry about Your toothbrush ain't next to my bathroom sink Can't sleep anymore in your t-shirt I'll write out "I miss you" then press delete You're not supposed to miss me I'm the ex-girlfriend Not even your friend I'll forget about your birthday Coming up next week Your sister's tryna call me but I let it ring 'Cause it's too hard to think About how hard it's gonna be Not being yours I still can't believe I'm the ex-girlfriend Not even your friend I'm the ex-girlfriend Not even your friend
