I have this friend and we have been friends for a while now. I have told her in the past that I liked her and she really didn't say anything back to me. We work together and she sits next to my desk and when ever she has a break or something I catch her looking at me I look back at her and smile and she smiles back. When it's around lunch time she will wait around for me and then ask me to lunch. I always say yes because I like eating lunch with her its like a thing that I look forward to. We even hangout outside of work and she always teases me and shoves me and she even said that I make her feel better when she is in a bad mood. She also uses a lot of smiley faces while she talks to me through text messaging. I catch her staring at me a lot. I just don't know what the signs are. Could I be just imagining it or what?
