She's not in love with him.
She was never in love with him. Not when she first met him, not when his wife left him for the first time, not when she came back from Oregon, not when he went back to his wife, not when the divorce was final.
Never.
She was definitely not in love with him when he hugged her after his fifth child was born.
But when he kisses her, she calls herself a liar.
She's not in love with him.
Maybe she is.
