I am kind of seeing this new girl. We hang out constantly, hook up. The only thing is that around our other friends we don't act like anything more than friends. This is even though our other friends know we are hooking up/hanging out. I am definitely into her and want a relationship at some point, but I just get mixed signals. She was one of my very good friends before we started to like each other or whatever, I know she is into me, but we act like nothing is going on in front of people. I am 21 years old, in college, if that helps. Thoughts?
