I Should Know By Now

I should know by now
You don't really love me
Or think that highly of me

I should know somehow
You don't want me only
You just say that
When you're lonely

I hear your voice
And I forget again
That your hello means
Goodbye in the end

Still I believe somehow
But I should know by now

And I should see the light
But it's so hard to do
When all I see is you

And I should do what's right
But I keep on believin'
This time you won't be leaving

I'm just a fool
A fool where you're concerned
But that's a lesson
I can' seem to learn

Someone show me how
'Cause I should know by now

I'm just a fool
A fool where you're concerned
That's a lesson
I can' seem to learn

Someone show me how
'Cause I should know by now
