What did I do wrong?

Hi!
So I was talking to this girl on IG for a week. We don't know each other, she knows a lot of my friends and we share the same interests. We never talked in real life even tho we do see each other driving by, she hangs out at a place close to where I hang out with friends. She seems cool, she also loves cars and drives the same one I have. She always replies with interest and long texts, she even saw me drift my car which wasn't planned but she said thought it was awesome and all.

She also checked me out a few times. Well so I still needed to talk to her in real life but didn't have the balls for it. There were moments where I could've easily talked to her but didn't do so. It even seemed that she was looking for me, we were parked next to each other and I saw her looking at my car then looking around to find me and I believe she saw me cause she kept standing there looking my direction (it was dark tho). My friend pushed me to talk to her but when we got to the cars she was already inside her car but just on her phone, still could've done it but I didn't.

Anyway everything went fine till yesterday.

We were talking about stuff and then I just asked for her snapchat, well she still hasn't opened it. And i'm sure she's read it somehow. I didn't do anything strange.. what now? I actually really like her. (We're both early 20s)
