20s+ would he think anything of it? (will answer back)?

So there;s this guy at uni who I like. I was randomly allocated into his group for an assignment- and pretty much any conversation that we had was around that (although I did try bring in a bit of flirt- but it wasn;t much). We recently were off from uni for four weeks for prac (we're studying teaching). During the middle of it I messaged him and added him on facebook- asking how prac was going. He doesnt really use fb that much and so the conversation kind of stopped after a few messages. Since we've been back (2 weeks) we haven't really had a chance where we can talk- we've maybe caught eeach others eyes once or twice in class when something was said by a peer...

but I'm just wondering- was it weird of me to have added and messaged him? is it weird that we've not really talked? whatcould he be thinking?
