I work with this girl, whose name I can't say. Over the couple of months that I have worked with her I have started to develop feelings for her. Sometimes we flirt and play around but I have not told her I like her. I would like to tell her but I just can't bring myself to actually make the words come out of my mouth and that is not the only problem - she has a boyfriend. Although I know that she knows I like her as more than a friend by the way I treat her and talk to her, I can never say it and find out whether she likes me too. What do I do?
