The guy[31m] I've recently started seeing makes me[21f] feel dumb and extremely insecure.

I've recently gone on several dates with this guy. We have similar interests, he's super handsome, he has a lot of cool artistic hobbies, and he is really smart. And all these things make me feel like shit about myself. I don't really have any hobbies because I work so much. I never went to college. I feel so stupid around him, like I can't contribute any meaningful conversation. He makes me feel so inadequate and it's not his fault, it's completely my own. He is polite, kind, affectionate and I can't get out of my negative head space to appreciate those things. Half the time I'm with him I'm just thinking about how idiotic I sound. Relationships should make you feel good and my insecurities are killing pretty much all the joy in this. I'd like to keep seeing him, and for some unknown reason he wants to keep seeing me. I just don't wanna feel so shitty and I don't know if there's anything I can do to stop that besides ending things.

tl;dr: Guy I'm seeing inadvertently makes me feel like shit because he's interesting and smart.
