know IT all

Somebody told me that you found somebody new and youre happy
You were never really very good at being alone
Apparently, its getting serious, so whatever that means
I bet you told him I was just somebody you used to know

I know he doesnt know it all
No, he dont know that you and me had something chemical
The things you said to me when we were drunk in Montreal
I bet you told him about me, but I know he doesnt know it all

Do you remember when the world was in the walls of your bedroom?
And everything you said to me was like a line in a song
I still remember what it felt like the first time I had you
And now he probably thinks that all your feelings for me are gone, and maybe theyre gone

I know he doesnt know it all
No, he dont know that you and me had something chemical
The things you said to me when we were drunk in Montreal
I bet you told him about me, about me
But I know he doesnt know it all
Like why you love the color yellow but you hate the song
And how you told me I would always be the only one
I bet you told him about me, but I know he doesnt know it all

Honestly, I hope youre happy, hope youre doing well
Ill still keep your secrets even though youre with someone else

I know he doesnt know it all
No, he dont know that you and me had something chemical
The things you said to me when we were drunk in Montreal
I bet you told him about me, about me
But I know he doesnt know it all
Like why you love the color yellow but you hate the song
And how you told me I would always be the only one
I bet you told him about me, but I know he doesnt know it all
I know he doesnt know it all
I know he doesnt know it all
