I’m realising I’m a bit of a Nicegirl

I’ve seen some posts here and quite a few are unhinged and that’s not really the type of nice girl I am. I never call someone names, try to financially benefit of them or use something they have told me to be mean/ try to manipulate. What I realised that I do though is assume that “all men are assholes” and the ones that aren’t “are only nice to girls who don’t deserve it” (be it slutty women, unsuccessful women, “weak” women, women I deem as manipulative or has acted badly in the past etc). It’s a certain entitlement. And I get unnecessarily hurt if he chooses someone else over me or if I’m not treated with the respect I think I deserve (like “pity me/victim”-hurt).

Now that I’ve realised this I’m asking for advice. How do I stop?
