The man named Lye said he was there to watch a game when he saw the woman sending messages like'I wish I was with you all day' and 'I will see you as soon as I am done with him', and couldn't help himself but tell the woman's partner at the end of the game what she'd been up to.
He then later posted his experience on Facebook, explaining to his followers what happened and even shared a photo of the note he sent to the man and a picture of the couple at the game.
