She always seemed quite interested in going to the movies, meeting for a drink or whatever, but due to the fact that I was travelling quite a bit for work reasons on the weekends and she was preparing for exams during the week, this didn't materialize until late in January.

Let me guess. First you hesitantly probed about going out sometime, probably a time when you knew you'd be traveling soon, and when she indicated interest you said, "Cool, unfortunately I'll be traveling soon, but some other time definitely" and stopped showing effort for a while, then asked her again later and immediately gave up when she tested you with "Oh, I've got some exams..." Then when you go out, you play it safe by having completely platonic conversations and not touching her at all, leaving her wondering whether you're gay or just want to be friends.

But last time, she casually mentioned that she now has a boyfriend (who lives in the same city). The weird thing is that she didn't do this in a "Look-we-must-talk-I-have-a-boyfriend-now-so-we-should-stop-meeting-the-way-we-recently-did" sort of way, but it was more like "Tonight was great as usual, when will we next go out? Oh, next Thursday is bad, I've already promised my new boyfriend to do [whatever it was]".

Then at some point she gets fed up wondering and just decides to lay the "boyfriend" card out there to see how you react, at which point you probably react with meek confusion and stop trying to show any inappropriate affections towards her, while still being friendly. Hello friend.
