How long is forever

I fell too hard and much too deep in love with you
I let you come and go at will it seems
You're back again this time you say forever
But I wonder just how long forever means
How long is forever this time
How long until one night you don't come home again
How long is forever this time how long until I'm all alone again
[ steel ]
People say I'm foolish when I take you back
And it could be they're right but who can say
You'll be welcome here within my arms forever
Even when forever ends for me today
How long is forever this time...
