What am I doing wrong?

I’m a 31 yo male and I’d like to think I’m pretty normal. But here I am asking reddit for advice. I never had many girls interested in me in my younger days and now it continues to be like that with women now. I try to be the nicest person possible and very respectful even though it seems rude arrogant guys get all the attention. At this point, I don’t wanna go out looking to no prevail. Anyone have any advice or places I should try meeting people?
