Mistake

At what point does he realise?
Is it when he wakes to find she has left no word?
No gentle mailed reminder of her gorgeous presence.
Is it when he points the car towards the office and the first song on the radio has an image of her in every line?
Is it when he finds himself comparing every woman he sees with the absolute glory of her face and form and finding others utterly wanting?
Is it when her smile and scent dull his defences and he can’t stop her from climbing into his thoughts and curling up in his heart?
Is it when he goes to sleep and she is the last thing he thinks of as he closes his tired eyes?
At what point does he realise
He has made such a stupid mistake?
