Lyrics of Unless you're sure

I try to wipe the worry off my face
Hide the tears so they fall without a trace
How am i supposed to know if you're staying with me because you're sure

Unavoidable is what they say
In the end do all things have to fade?
How am i supposed to know if you're staying with me because you're sure

Before now i was fine not knowing the outcome of all this
People say why mess with a good thing?
But it's not good enough unless you're sure

When you fall asleep inside me arms
I could stay forever in that warmth
How am i supposed to know if you're staying with me because you're sure

I hesitate asking you for an answer
I wouldn't know what to say
And i know this really shouldn't matter
I couldn't bear it anyway unless you're sure
Unless you're sure
Unless you're sure
