Most women are very sensitive to their flaws and imperfections. Insecure women are even more sensitive to their flaws, especially with their bodies and when they approach the wall.

If you treat her like she's the perfect girl and the only person in the world for you while she's feeling shit she subconsciously pick up two things:

  1. If you're impressed with low quality shit that means you're even lower quality shit.
  2. You're low quality shit so she'll treat you like shit because you think you deserve it.

Understand that women are people too. Some are really disgusting as well. They can take a bigger shits than us, smell bad, have poor hygiene, be absolutely bitchy, break down under pressure, etc. Most women know that they aren't the prettiest person in the world which endangers their hypergamy because prettier women will get the highest value males.

So just chill the fuck out man. If you're insecure about your shortcomings, guess what? Most women and beta men are too. RP men are not that insecure because they're stoic, have frame and actively try to be the best they can be. Now being confident has the reverse subconscious effect on them:

  1. He's confident about himself which means he must have a lot of things going for him (not always entirely true)
  2. I'm insecure about myself while he's not, so he must have more value than me.

TLDR; Don't treat her like she's perfect because nobody is and she knows it.
