For someone inexperienced, why do I feel resentment towards the opposite sex?

30F and I’ve always kind of felt this way, it was kind of an ick that started in my teens and now it’s a matter of feeling full blown turned off present day. I don’t have daddy issues, i mean he annoys me a lot but not to the point where I don’t feel as if I can’t depend on him. My mom didn’t have a relationship with her dad and kept on reiterating that I have a good dad, we’ve had our ups and downs but I do think he’s a good person. I don’t like my mom’s bf, they’ve been together since I was a little kid and we’ve never fully gotten along since he was in the picture. I’d like to think if my dad wasn’t around, maybe this would have more of an effect on me.

I’ve only ever had one STR in my early twenties, another instance where everyone around me claimed this was a good guy but I just..had my doubts. It was a mutual break up because I wasn’t all in from the start, it’s like I just feel like I’m not meant to be with a man considering how I feel about them + I’m this old without a LTR under my belt. I don’t think I can see myself with a woman, I’ve only met men through the OLD apps and guys I would consider have shown interest since the last person. I just tell myself it won’t work out & feel like I’m meant to be alone so I find a way to subtly stop it in its tracks (that’s if the guy doesn’t call it quits beforehand).

I’m told I’m attractive but being this old and never being approached by quality guys in person (apps don’t count), on top of hearing all the shady things men have done with their SOs, I just don’t know how women can trust them enough to want to be in a romantic relationship with one. I’ve never experienced being cheated on or domestic violence etc…so why do I deep down have suspicions towards the male species as a whole? Is this normal?
