Chemistry

Is this where it ends
Why couldn't I give in
'Til I find you back with me
Beneath our walls is chemistry
And if it weren't for yesterday
Would you still believe in me
I'm begging for your reasoning
Did you love me anyway
If it weren't for yesterday
Would you still believe in me
Doesn't she fail
Doesn't she falter
When I'm not around
She makes me feel like falling down
Doesn't she fail or falter
When she calls my name
And I'm not there to ease the pain
