Until Youre Mine Tab

FIRST LET ME CLARIFY THAT I'M NOT A DEMI FAN, PER SAY.
I just know that I really wanted to know how the song was played, so I assume others do too.
It definitely isn't 100%, so pleeeease make corrections if you have any.

Don't know the bridge yet.
Tell me it if you've figured it out, I assume it's derived from the above.
