Lyrics:

How can I be sure ?
When your intrusions' my illusion
How can I be sure
When all the time you changed my mind
I asked for more and more
How can I be sure

When you don't give me love
You gave me Pale shelter
You don't give me love
You give me cold hands
And I can't operate on this failure
When all I wanna be is
Complete[ly] (in) command

How can I be sure
For all you say you keep me waiting
How can I be sure
When all you do is see me through
I asked for more and more
How can I be sure

I've been here before
There is no why, no need to try
I thought you had it all
I'm calling you, I'm calling you
I ask for more and more
How can I be sure
