I don't want to believe it is love

I thought it was just for fun
I believed I'd never fall in love
You were just another notch on the gun
But we went over and above
We wanted to run and run
Burning nights in our alcove
We shone like the sun
I was not enough brave
To bear such emotions overdone
I got lost in the love cave
Any chance to escape? None!
I don't know how to behave
I don't want to believe it is love
But far from you, I can't breathe
Please, please don't leave
If you go away, you'll be my death
Cause without you, I cannot live.
