How?

When i saw you today
I didn't quite know what to say
I didn't know how to act
Things were so different between us than in the past
It's the first time i've seen you since you broke my heart
I wish we could go back to the start
When everything was so great
Back before i felt our love break

What happens now?
Please tell me how
How am i supposed to go on
Now that you're gone?
I don't know what you expect me to do
Now that i no longer have you
