I woke up today to “What’s it like third wheeling in your own relationship?” 
Let it go, she’s just your girl best friend, but I’m questioning how strong my patience is 
Tipsy touching at the dance
Could you keep it in your pants?
You two showed up matching like you’ve been her man 
I say nothing and I go to bed
Knowing if I did who you’d replace me with

Don’t come off controlling 
They’ll all call me crazy
Do you think I’m boring?
Is it a chore to date me?
I know she’s important 
I hate ultimatums 
I just wish that you found me 
A bit as entertaining 

I don’t want to judge her
But I can’t be naive 
When I see your initials hearted underneath her sleeve
Trust you? Yеah right 
We all know that friends turn into lovers ovеrnight  

“She’s like a sister”, it’s “business”, you’ve got baggage only she can lift?
Let it go, you’re just her guy best friend... that all of her girls dare her to get with 
You’ve got a hickey on your neck
Could you be hiding it less?
Everyone assumes that I just got messy 
You claim it’s just from a cooking wreck
Who knew dinner meant the outline of her lips
Don’t act like your jealous 
They’ll call you psychotic 
But I shouldn’t be wondering 
Who you will go to prom with 
You say she’s relaxed 
Hey! I can be laid back babe
I take it like a champ when she’s stabbing me in the back - wait

I don’t want to judge her
But I can’t be naive 
When I see your initials hearted underneath her sleeve
Trust you? Yeah right 
We all know that friends turn into lovers overnight, yeah
We all know that friends turn into lovers overnight  

Friends to lovers, hey we were that too
Always swore it was platonic ‘til I wound up in your room
You're “just friends”, hey lover, up and down you swore 
But she’s bolder, brighter, nothing like the girl you’re calling yours

I don’t want to judge her
But I can’t be naive 
When I see your initials hearted underneath her sleeve
Trust you? Yeah right 
We all know that friends turn into lovers overnight, yeah
Funny how my intuition always turns out right  
I didn’t know exclusive meant exclude me from your life, boy
We all know that friends turn into lovers overnight
