Shadix, if you want to change yourself to be a more desirable prospect the main thing you need to change is your thoughts.

You make sweeping assumptions about women. You ignore anyone who points out that your generalization doesn't apply to them. You latch on to statements that confirm your bias.

You have a clear dislike of society as a whole. You are overly preoccupied with age and appearance. You blame everything on whatever you can - society, women, past trauma. Yet you don't challenge your thoughts that have been influenced by your past, so you can never get past them.

Those things.... They show up in interactions. You might not think they do, but they probably do to some extent. If nothing else, you deprive yourself of opportunities due to your negative beliefs. You either intentionally prevent yourself from opportunities, but you likely subtlety do it too.

You don't need to change how you look. You don't need to change your level of introversion or extroversion. You don't need to change your interests.

You unfortunately need to change the hardest things to change - your core beliefs. Those are what I need to change as well - I've changed my behaviours but I have not been nearly as successful in changing how I think about myself. And the way I think about myself plays a major role in my struggles.
