Normally, attractive women date equally within their lookscale. Looksmatch couple.
If you ever see an average to below ugly dude with a hot chick, it's because of the following:
1. They were hs sweethearts
2. They met through social circle
3. He pay her (prostis)
If she break up with him, he will no longer be able to find another girl like that. She can easily date up because of her looks. Unfortunately this isn't true for the guy. Attractive women has tons of suitors. Men are willing to settle less. If he is ugly, he cannot replicate his result on a predictable and consistent rate. Good looking guys dont have this problem. Either spam approach or move to 3rd world countries.
I'll write more later on those 3 points. Won't have access to my phone til later.
