My sister is stunning she is 6yrs younger than me, tall slim and has bigger boobs than average as she had hormone issues in her teens. She's beautiful. My partner when we first got together as friends used to make remarks about her all the time then when we started dating I couldn't get them out of my head. He even said a few times I looked like her face. I am short with 34B boobs. My sister wears make up takes care of herself wears perfume and has long blonde hair. I don't wear make up, or perfume and my fav outfit is black jeans and a T-shirt.
I know full well he fancies her and she's more his type. What the hell do I do??
I love my sister so much but this feeling won't piss off. I hate him seeing pics of her on my social media when we have days together etc it kills me.
I broke up with him because of these feelings and he told me I was being silly and I'm prettier etc but I don't want to be prettier I just don't want to constantly feel like he's lusting over her.
Should I end it? I know it's extreme but he doesn't deserve me being upset and grumpy in these situations and I can't resolve these feelings at all.
