[Verse 1]
I was always the one
Throwing my hands up
Running and saying I'm done
Heartbreak red-handed
Holding a smoking gun
Got used to my seat at the table
Til the tables turned
And honestly, this feels worse

[Chorus]
You were always supposed to be my seatbelt when we crashed
Answering the questions that I didn't have to ask
I was supposed to be the concrete heart that couldn't crack
And you were supposed to be the one, yeah

[Verse 2]
I was always the one
Closed off, independent
Never believed in love
Til you tore my walls
Brick by brick, built me back up
You loved me til I knew who I was
And you proved me wrong
Until you proved me wrong

[Chorus]
You were always supposed to be my seatbelt when we crashed
Answering the questions that I didn't have to ask
I was supposed to be the concrete heart that couldn't crack
And you were supposed to be the one, yeah
And you were supposed to be the one, yeah

[Bridge]
You were supposed to be my anchor
Now you're just a stranger
Running around kissing strangers, oh
I was supposed to be the bad guy
But turns out I couldn't if I tried
And damn it, I hate being on the other side, oh

[Chorus]
You were always supposed to be my seatbelt when we crashed
Answering the questions that I didn't have to ask
I was supposed to be the concrete heart that couldn't crack
Yeah, you were always supposed to be on my side of the war
Tell me what the hell were the last five years for
Now we're just broken hearts and slamming doors
And you were supposed to be the one
You were supposed to be the one
You were supposed to be the one
