Sometimes people mix up the order of things and thus the cause and effect. For instance, with some medical issues, doctors have thought things like “oh, you went on this extreme diet, then you lost weight and had gastric issues”. No, I lost weight and had gastric issues, so I went on an extreme diet. In this case, i think the misogyny precedes lack of success at finding a partner. It can also be a situation of giving up too soon. For me, middle school and high school were so horrible in various ways that i assumed I was 100% doomed - I didn’t realize that life after 20 is very different. It still has high school social aspects, but it’s a lot better in many ways.
