What should I do?

Hi, I work at a restaurant as a host. This new girl started working there about a month ago and the first time I talked to her, I felt something special. She is a server. I told a few of my closest co-worker friends that I had a huge crush on her and they all told me to go for it because they think she likes me too. All the hosts including myself agree that she acts different around me than everyone else. She is flirty, stands close to me, and always comes out to the desk to talk to me when I'm by myself. When I'm in a different room, she will come find me if she hears I'm working just to talk. I added her on facebook and we have been talking for about a month now, but she has never messaged me first. She'll respond within minutes if I message her, but we've only had a few long conversations and then eventually she won't write back until the next time I message her. I don't have her number yet either. She likes everything I post on facebook also. I invited her to join me and my co-worker to play tennis two weeks ago and she said yes. She seemed excited to play and was telling me what she was going to wear and what she looks cute in. We had a great time that night and talked for an hour after my friend left. She seems to talk a lot more in person than online. However, everytime I bring up anything related to her and I, she won't talk about it. Another server that works with us is her close friend and she will tell her everything. So, the other server has been talking to her a lot about us and trying to help make it work. From what I am told, she likes me, but she just got out of a bad relationship and is afraid to get hurt. The other server told my crush that I am a sweetheart and would treat her like a princess. This past weekend, we were talking and she asked me if it was true that I liked her. She wanted me to spill everything I was thinking, so I gave her a long, heartfelt message that explained everything from the beginning to present and she said it was the sweetest thing she has ever read and that no guy has ever talked like that to her before. That weekend we worked together three days in a row and she was very talkative and nice to me. Everytime I ask her to do something, she will start to make plans, but they always fall through. She told her server friend she is ready to move on and settle down with a sweetheart guy who is funny and really nice. All of that describes me perfectly. She is somewhat out of my league, but I have everything she wants, plus the confidence to go with it. I'm trying to get her to do something with me a few times before college starts back up, but it just isn't working. Plus, when she doesn't write back I don't want to message again because I will feel pushy, but I don't know what to do. I think maybe she is nervous and wants to take it slow and I'm cool with that, but she still doesn't talk much outside of when I see her at work. I don't go after many girls, just the few I feel a connection with. I definitely feel something with this girl and even though we've only hung out once outside of work, I like her a lot. She makes me happy and I like spending time with her. It just seems like half of me says move on, she's not interested and the other half says yes she is, she shows all the signs, just wait for her. Any advice? What should I do? Thank you so much!

If your post is true in every detail, then wait for her. In situations like this, listen to your gut instinct.
