Do you think this girl likes me?

I do a lot of the same thing with a guy I recently liked but I don't anymore... But anyways we had small conversations ourselves and if he was sitting across the room I would look at him too and if he caught me I would look away quickly or pretend I was just absent mindedly looking around. I would be pretty angry if he also grinded someone else. But I would still say happy birthday to him. Maybe she just forgot to say happy birthday. I didn't think the guy I had a crush on liked me back because it didn't seem like it with all the little conversations we had and how he was shy. Maybe she feels the same way. Plan to do something like as friends with her in a group and ask for her phone number. Once you got it you can start texting her and become closer. Make a move because I was way too shy to make one on my crush. Shes probably shy too! I think she definitely likes you! :)
