So I have a crush on this girl in my college class. She's very quiet, shy and reserved. I noticed that she always sits in the corner of the classroom with a friend, and rarely strikes a conversation with anyone. Right after class -- boom -- she's gone; never stays to chitchat. She's always got a poker face on, and hardly talks to anyone in class outside of her 2-3 close friends. However, we seem to make eye contact a lot, and she always smiles and waves at me whenever we cross paths. So, I know that she at least doesn't dislike me lol.
About a week or two ago, I was shopping at a local farmer's market with a friend. Apparently, she was there that day and saw me, but I didn't find out until a few days later in class when she asked me if I was also there that day. When I asked her why she didn't come up and say "hi", she answered that she wasn't sure it was me and didn't want to embarrass herself. That was the first time we actually engaged in some form of conversation.
Since then, we talk here and there after class, but I always feel like I'm walking on eggshells when we do, mostly because I'm not sure if she's actually interested in me or just being friendly...that, and the fact that she's always with a friend, which makes it harder to, I guess, make a move. We've also taken the same taxi to school on several occasions, but...guess what? Her friend is always there as well.
Anyway, so my question is, does she seem interested in me, and secondly, how in the world do I even ask out such a shy girl? Maybe start out by eating lunch with her at school or something? Should I ask for her number? I've been rejected many times by shy girls, so my confidence is really low when it comes to interacting with them now.....
