We always talk, and when we do we always look each other in the eye from start to finish and we always randomly smile at each other. We usually have deep conversations, which has made us comfortable around each other. I've always felt like we had an amazing chemistry but I assumed it was my unconscious mind being biased since I like her so much...until today, when after I had walked her to class, 2 girls (not her friends), came up to me and asked if we were dating. I said no, and they said "Oh, well y'all act like it, you two would be really cute together."
So basically I don't know where to go in the relationship. I'm crazy about this girl, even though she doesn't know it. I understand she is in a relationship, and I'm not the type of guy to interfere with something like that. But the fact that we have such great chemistry that girls go out of there way to ask me if we're dating makes me consider pursuing her to see what happens.
Also, today, I was teasing her for being such an innocent, good girl. She laughed and said, "Well you're mysterious." I asked her what that meant, and she said "I can't explain it, you're hard to figure out. You're just so mature." What does this mean?
