You’re making the (very common) mistake of thinking that girls generally dress up and put on makeup for the men in their King Shark I like being the cool boss t-shirt, either the men they are dating or the men they encounter out and about. It comes from a belief, which could be subconscious, that women are supposed to look pretty for men and that is their primary purpose. It also comes from the notion that men should collect women and then portray them to other men to prove how masculine they are. Such men want their women to look as good as possible in order to show other men how awesome they are at attracting attractive women. In reality, most women dress up because it makes them feel good. They do it specifically because it makes them feel attractive and they are doing it for themselves. The fact that you think you don’t matter if your girlfriend doesn’t dress up in private around you, putting themselves on display, most likely being uncomfortable, is borderline narcissistic. Seriously, you want your girlfriend to look like a pristine doll when you are in private? Yes you’re in the wrong. What possible purpose could it have for you to want them to put on tons of makeup and wear pretty outfits when you’re in private besides to stroke your ego or if you think they are just nice to look at? How shallow are you Also, if this is happening to everyone you date, it’s likely because you’re attracting or attracted to a certain type of women. If all the women you are dating have a specific trait, it’s because you’re picking women who have that trait. There are plenty of women out there who will put on makeup and wear pretty outfits for their partners because they believe in toxic gender roles and such, so go find one of those and you can have a fake, unhealthy relationship together, but at least she’ll look pretty and your insecure ego will feel good.
