How does an extremely shy girl act around a guy she likes??

Just so you know, this is coming from a shy girl.
If a shy girl likes a guy she:
-might start fidgeting around uncomfortably in her seat when you walk by
-she may turn bright red when you are around
-she might avoid your gaze at all costs (this could also be a sign that she doesn't like you)
-she will attempt eye contact for as long as she can bear to hold it
-she might seem to "shine" a little bit more in her group of friends
-she may look at you and when you notice her looking she will quickly turn her head

1. As far as just telling a shy girl you want to date her, I wouldn't recommend it because it will make her nervous and she will have no idea what to say. It would just be uncomfortable for her. Ask her if she wants to hang out with you and go see a movie or something. This is a lot less stressful for her because then all she has to do is say yes or no.

2.it could be a bad sign that she doesn't come talk to you during her free time but it might not be. She may want you to see her walking past you just to let you know she's not interested, or she may be doing this because she is too shy to initiate a conversation. If she is showing some of the signs that I listed above, she probably is just too shy to initiate a conversation, but if she isn't showing any of the signs, just move on.

Walking by you without saying anything is a sign that she likes you. She's probably hoping that you'll notice her and start the conversation because she's too nervous to do it herself--I'm pretty shy, and I've done that before.

If a guy just told me he wanted to date me, I think that would be a little awkward. I honestly wouldn't know how to react to such a forward statement. It's better to take things slowly with her. She's probably nervous about being the one to initiate things, so if you want to hang out with her during her lunch break, you'll have to approach her. Based on the way she tries to get you to notice her when she walks by, that's most likely what she wants anyway.

I'm generally shy. If a guy that I liked said that to me, I might be a little nervous to approach him, not because I don't want to talk to him, but just because of pure shyness. She may be hoping that you'll see her walking by and come to her, instead of the other way around. Have you thought that it could be her silent way of telling you that she's on break, without having to directly approach you?

I also hate to interrupt people when they're working, so if I want to talk to them but they look busy, I'll generally try some other time. I generally try to be around the guy I like, even if I have to approach him when he's alone. Other times, I'll stay by myself and hope he'll come to me.

She acts extremley shy but she seems like she's trying still
