How less do you have to think of someone to do this?

Ok so in total transparency I had low self esteem even before this relationship but during this relationship I started noticing signs here and there that my then girlfriend thought she was better and I was somehow inferior the interesting part she was wasn’t a super attractive girl she was mainly average and she didn’t take care of her appearance she was overweight and didn’t care about it she lived like a slob she would eat half containers of ice cream and chip bags and would leave the trash mixed in with piles of clothes on the ground. She would pick her nose, she would fart while she was eating or someone else was eating. Like this was a complete mindfuck because someone who exhibited all this still found themselves better then me and it made me question what actual girl I can get if it’s that bad

I feel at some point as a bare minimum you are above her because of these choices and behaviors
