So I met a girl at a friends house and we hit it off irl but she doesn’t really text back. What should I do?

(Me and this girl are both 17) I met this really funny and pretty girl at a friends house a little over a month ago. I've never felt this feeling before with any other girls and I really like her. We hit it off the first time we met and we talked a lot. The third time we met at my friends house (he has like “parties” i guess with our group of friends and his girlfriend’s group of friends) we were with each other the entire time and didn't stop talking to each other. (My friend and her best friend who are dating both said it seems like she likes me) The next day she added me in Snapchat and i try to start small talk but after a few messages she doesn't respond. About a week later I try to start more small talk and she stops responding after a few messages again and leaves me on delivered. I wait a few hours and text her back but about something else. She responds but again, after a few texts im just on delivered. Its been that was for around 6 hours as im writing this. I dont know if im just bad at typing over text or if she is just not interested? It hurts though cause every time we have talked in person it seems like she is into me and i really like being around her. I’m thinking about texting her exactly how i feel and asking her to hangout if she doesn't text back or anything in the next few days. Somebody please tell me what to do so i dont screw this up.
