I Can't Be Yours

I can't be yours if you can't be mine

Some might play along, but you know I'm not that kind

If I'm just gonna be a friend, a friend tells you when your toe is on the line

I can't be yours if you can't be mine

We've had some fun, and there could be so much more

But if she's the one, you can't keep knocking on my door

If I can't be there, then you can't be here

If you don't understand, then let me make this clear

I might play a little part in breaking her heart, but a vow I won't go near

If I can't be there, then you can't be here
