Immature

You knew just what you wanted

And I was over my head

And when you told me that you loved me

It was a bit overwhelming

It took a little too long

For me to figure things out

I guess that I was too late

'Cause now you're happy without me

Baby, won't you let me in?

I won't break your heart again

Learned from all my immature mistakes

I know it probably was my fault

Give me the blame, I'll take it all

Messed up once, I'll give it you straight

I promise you I've changed

I promise you I've changed

You say you're doing better

And that you're wishing me well

So I lie and say the same thing

Know it isn't helping

I shouldn't have told you that I'm fine

Baby, won't you let me in?

I won't break your heart again

Learned from all my immature mistakes

I know it probably was my fault

Give me the blame, I'll take it all

Messed up once, I'll give it you straight

I promise you I've changed

I promise you I've changed

I'd give the world

I would do anything to make it up to you

I wanna make it up to you

Baby, won't you let me in?

I won't break your heart again

Learned from all my immature mistakes

I know it probably was my fault

Give me the blame, I'll take it all

Messed up once, I'll give it you straight

I promise you I've changed

I promise you I've changed
