I had been cheated on by my now ex and father of our young son with a couple of women. He used to call me fat but the girls he cheated on me with, were the same size or slightly bigger. I realise now this was the wrong question to ask but at the time I was very hurt and not in a good way at all. I asked my friend why he called me fat but cheated with girls of the same size and she replied “maybe he can’t get a skinny girl”. I didn’t say anything at the time but it’s been about a year and I still can’t forget it. She’s insulted me on a few other occasions but that is the thing is find hard to move past. AIBU?
