Dating advice?

I’m trying to work on myself but I was at the bar 2 nights ago, and I wasn’t trying to attract anyone I was just trying to have fun with my friends. And then I run into this girl, and I find out that she goes to my college and she’s from the same hometown as me. And we were kinda vibing together and we started dancing and then we started kissing eachother.

By the end of the night she wanted me and my friends to come over and smoke, and I started thinking she might’ve wanted to hookup or something. But I don’t know, after I started feeling like we kinda weren’t vibing anymore. When we got to her place she kinda just stayed by her roommate while we talked and smoked. And then we we decided to go back home, we just hugged eachother and left. I hope I didn’t do anything that weirded her out. We just smoked

I only got her snapchat, and I kinda want hit her up to hangout and see where things go, but I just feel like she lost interest. I don’t want to get all caught up in this but should I text her or should I just leave it alone and go on about my buisness. She was a hella cute girl but I just don’t think she’s feeling me anymore. But say if I’m in another similar situation later on in life how do I keep her into me whether to hookup or to ask her out
