There's this girl that I'm really into, but she's taken. I thought that she was interested in me through her signs (hugging me all the time, calling me cute, touching my hair etc.). But she's currently dating this guy. We talked about her relationship today and the whole time she had a smile on her face - I think she's genuinely happy with him. It's just really discouraging and makes me want to forget about her. I don't know if she's just being open and friendly with me or if she really has feelings. Things would be so much easier if I could just stop liking her, but I can't. It's so hard to forget her, and some part of me still thinks that I have a chance. What should I do? Should I try my best to move on, or do you think I should stick around and see what happens?
