I've gotten to know a girl in one of my classes a little bit. She's pretty cool and I'd like to hang out with her. However, the semester is basically over so that's not going to happen. We only have two weeks between Thanksgiving Break and finals and I was pretty busy during this period, so I couldn't really ask her out (where or when would I be able to do anything?). However, if girls can read guys as well as some of you say, then I'm going to have to assume she has a hunch I "like" her.
I feel I've been receiving mixed signals. We have the class twice a week (different setting depending on day of the week). One of the days, I don't have a chance to really talk to her much (if we do talk, I'm usually starting the convo this day). As for the other day, we have no trouble talking, there's a good amount of quality time there (and she starts the convo just as much as I do). While her kino has subsided a little, her body language has improved.
I knew today was the last day I'd see her before break (now it's finals time, we don't have a test in our class), so as we were leaving, I said to her, "Hey, we're always together in class, let's hang out
outside of the classroom next semester." She smiled and we parted ways. WHAT IS THIS?

If I heard a, "yeah, sounds great!," then I'd be happy lol. We exchanged numbers a few weeks back and have texted/called a couple times,
what's the best way to keep in touch with her over break?
