Don't you hate this: when you find out he was interested it is too late - or is it?

So I've been friends with a guy who I attend grad school with for a semester now. Toward the end of last semester, he asked me to help him with a class and offered we do it over coffee. We met up at school instead, but I forgot about the coffee so we finished up at school. At the meeting, I saw he was flirting but I wasn't completely sure. On another occasion, we saw each other in the library after I gave him a book, he followed me into the elevator. I asked him what floor he was going to since he didn’t press a floor number. I thought he forgot to hit a floor number! He joked that he was following me but I didn't know how to respond - I smiled – but I think he wanted to hang out/study together. WHY DIDN’T HE JUST SAY THAT?! He hit a floor and exited the elevator after saying bye. I guess he took that as I wasn't interested. But I am! It's just that I'm not good at reading "signals."

 

After the elevator incident, I came to the conclusion that he was interested but it was almost "too late." During the holidays, I asked him by email to look over my thesis and I asked him to go for coffee at the end of the email. He looked over my thesis extensively - it was sweet - and he told me to text him about the thesis, but said nothing about my coffee invite. I figured he overlooked my invite.

 

I texted him 3 wks after that and told him I'll buy him coffee because I wanted to thank him for editing my paper so well. But it was at the start of the new semester and he emailed me back and said that he was just getting his books and it was a crazy week. He also said "we can hang out sometime after I get settled into my schedule." I told him to contact me if and when he was down to hang out. But it's been three weeks and nothing. I see him at school and he seems nervous around me - he didn't use to be nervous. Will he come around? I would love to get to know him better.

 

What do you think happened here? And what should I do?
