first time dating outside my race and i keep overthinking everything lol

I’m 24, in Chicago, and I’ve been talking to this girl I met on Hinge for about a month. I’ve only dated within my own race before, so this is all kind of new for me. She’s super cool, we’ve gone to a couple coffee shops in Logan Square and one late-night taco spot in Pilsen, and honestly the vibe is great. But I keep catching myself overthinking dumb stuff, like whether I’m coming off awkward or if I’m supposed to act different because she’s from a different background. What’s messing with my head more is telling my parents. They’re not like super strict or anything, but I know they’re gonna have opinions. I’m not even sure if I should bring it up now or wait until it gets more serious. Has anyone else dealt with that weird mix of excitement and nerves? I really like her and don’t wanna ruin it by being in my own head all the time.
