Can a good samaritan please help me understand if a girl likes me?

There is an amazing and sweet girl who I really like a lot and I met her a couple of months ago and we get together with other friends sometimes and Snapchat each other occasionally. She invited me to a theme park last Saturday with a couple of other friends. Also, she is single currently and has been for a couple weeks. We are both still in high school. Here is some more information to help; we snapchat regularly and she sometimes waits a couple hours to reply and sometimes reply’s instantly. Our last few messages have been as follows: she posted to her snapchat story saying “send an X if you’re a guy” (it’s a thing where the poster will then send you a list of questions about them you have to answer). So I replied and she sent me the questions. I thought about them really carefully and tried to be flirty yet vague with my answers. She replied the next morning with “sounds good” while making an ‘okay’ sign with one of the hands. I then sent back a winking emoji “

Hi, I recommend you invite this girl on a programm to talk.(not a date) Talk about what you are interested in, but only after you ask her what she interested in. Don't trouble about the conversation topics, it will come naturally. And don't worry about your heart beating out of your chest, it means that you are LIVING! These are the moments in life when you truly feel what is important and what is not (:

Hey what u gonna do if she likes you? Are u going to take advantage of that if she does like u. It's clear she does like you. We get closer to those we like. *** if u love this girl and you think she also love you. Don't wait for her to tell you first. Man you have to boss-up and solve your problem.
