Taking sides

I see it in your eyes when the light is on
Staring out into space
I see it in goodbyes
Just before I've gone
Hoping I'll be gone for days

You say that you weren't looking for someone to
Come and sweep you off your feet
But given that's exactly what you have done
What would you have me believe?

The irony of course is that for many years
All the many times you stressed
You'd never be unfaithful to me
Who now would have guessed

The children aren't aware yet but I suspect
Back from university
Both will I imagine be taking sides
One on yours the other me

Ironic when you think
That for many years
You thought I had had an affair
Yet here I stand cap in hand
Somewhat the worse for wear

I'm terrified of losing you that's for sure
Still I understand your plight
A vacuum exists when you're on your own
And it needs to be put right
I won't give up without a fight
