Why is he interested in me?

I (22F) sometimes hangout with this guy (23M). He’s very handsome and he knows it. He sees different women, and also works in nightlife so he’s surrounded by gorgeous women. I think I’m cute but I’m the female jack black compared to them. We’re very different people. He’s a player. I take no issue with him playing the field. I respect his autonomy and care more about honesty. I’m not jealous of these women just confused.

At first he definitely followed whatever script he normally gives, but over hangouts it’s definitely changed.

Apparently I make him feel shy? He’s told me this more than once and that I’m also very direct. He seems more genuine with me now (though I always stay skeptical). He’s very respectful of me. He doesn’t try to push my boundaries. He drives me home. He is very chivalrous, but it’s not to get something out of me. He even serenaded me once which made me cringe but I also thought it was funny. He can tell I’ve been through a lot and he’s been very understanding to that. He was enthusiastic when I asked about seeing each other again. He has repeatedly asked me why I was on the apps, if I’m still on etc. He tells me to be true to myself.

I’ve been told I’m very open minded and curious. I like to listen to peoples lives and I don’t judge. People tend to vent to me about stuff or share things they wouldn’t tell most people. I’m a weird person too though tbh. I struggle with sarcasm, I sometimes say things that are inappropriate, and I definitely have some quirks. I feel like men like me less the more I talk. So it’s nice to be able to actually be myself around a guy.

This is just a causal thing but still very confused! I’m also ok with the arrangement. I don’t feel offended at all and it isn’t an insecurity issue. Sometimes I feel like a weirdo for not being bothered.
