Ex told me he was never going on holiday with me because my thighs were fat and I'd look horrible in a swimming costume... (At the time I was a size 12, very hourglass, and had tonnes of male attention constantly so I knew it was BS?an attempt to dent my self esteem - even knowing the psychology, it still hurt).
After I had our first child, he went on and on about a fortnight after I have given birth, that I was "a fat shitter". It was the least weight I ever put on in any pregnancy.
I was so unhappy with him, I didn't need to diet at all - my weight plummeted fast, post baby, because I just couldn't eat - despite breast-feeding baby for a year. It wasn't long before I had a 29" waist - much fatter than I had been when younger but still I was a nice size and shape. All excitedly, I told him I had measured my waist that morning, and guess what, it was back to 29" already? He snorted and said "Yeah, right. You have a 29 inch waist!"
When I was 18, I wrote a play for a competition at a very famous London theatre - the winning play would go into production. I got a letter back, saying that it hadn't won but they loved it so much they wanted to "put it into development". being young, naive and 200 miles away from London theatre, I had no idea what that was at the time (I later realised it was a huge thing and a honour!) and so I wrote back, a bit nettled, telling them not to bother. My brother - who had ambitions to be a writer but never made it - said to me, a couple of years later, and in front of a huge group of people "Ah but you're a failed writer!" Even at the time I knew an offer of having a play developed by a world famous theatre wasn't exactly 'failure'. But it made me feel shit. I had the last laugh. I now write non fiction and am published regularly all over the world. I'd imagine he still likes to think of me as "failed" because I am a jobbing writer, not J.K.Rowling. ;o) I think that stung so much as he knew that writing meant everything to me. And wanted to humiliate me in front of loads of other people.
My stepmother once said to my dad "You're not from a real family. What do you know about proper families?" He was an only child. But had 2 kids of his own and she had 4 kids. The irony was, all her kids remained childless and she has no grandkids. My dad was to have 7 grandkids. I think I know who ended up with the proper family.
