Is this love a lie

Is this love a lie
How would I know
So smile,
Tell me a lie
Saying it'll be alright
But by night,
My heart won't be able to fight
From this night of pain
There's nothing to be gained
So save me the heartache
Cause' I don't wanna break
But I might,
If you don't fight
Before night
Would you tell me,
If this love is a lie
