The message is brutal even by Tinder's standards and Michelle says she was left "in floods of tears". It took her several days just to take it in and muster up a reply.

However, she felt obliged to respond publicly because her date has a 13-year-old daughter - and she wants him to build her confidence and self-esteem, rather than knock or destroy it with the negative body attitude he displayed in his letter.

"You don't have to fancy me," Michelle, who describes herself as a Welsh feminist and writer, says. "We all have a good friend who we look at ruefully and think 'you're lovely, but you just don't tickle my pickle'.

"... but the forensic detail in which you express your disgust at my body is truly grotesque. The only possible objective for writing it is to wound me.

"And I'm ashamed to say, for a few moments, it worked. You stirred a dormant fear that every woman who was ever a teenage girl has – that it doesn't matter how funny you are, how clever, how kind, how passionate, how loyal, how determined or adventurous or vibrant – if you're a stone overweight, no one will ever find you desirable."
