Crush on this teacher? Help?

[Reporter]

Over the past year, I had this crush on this teacher. She is damn pretty and beautiful. I like her very much. She is a very good teacher .She was my old chemistry teacher at school. So here is the main story-
I have this habit adding my old teachers on facebook. I added her. She accepted my friend request. But then after like 2 weeks, I noticed that she isn't my friend on facebook. I got kind of worried why she deleted me. I am not that kind of a guy who would put pictures me and like bad or inappropriate pages on facebook. So I am wondering. A few days back , I and 3 of my friends were in mall and we encountered her. She didn't look at any one in particular but she looked me, I smiled and she smiled and she went by.She just looked at me and smiled.

So does this anything to with facebook thing ? I am worried. A lot of my other friends ( girls) added her in facbook. But why did she delete me and she smiled as if she doesn't realize the facebook thing. My friends who were with me at the mall, they know her too. Don't tell me this illegal and all. Just tell me if she had feelings for me ?

U r thinking about it to much. And honestly it's never gonna happen so just get over her

She may have feelings for you, but maybe she does not want everybody on facebook to know this. Try to contact her another way and see if she does.
