Guy will text me then stop then start again. Should I be worried?

Anonymous
This guy that I’ve been crushing on (and I think he likes me too, I’m definitely sure he is attracted to me) will text me sometimes with updates on his life, work. He even sends me pictures from his office and shares products he’s working on with me. Conversation is going well, then he’ll suddenly cut it short and not text for 2-4 weeks. Then he’ll pick up right where he left off. I do text him as well, and the same issue: sometimes he’ll be every enthusiastically texting or sometimes he’s short (but still polite).
Should I be concerned?

I had asked him if I get to see him before he graduates and he said that he was down to get coffee or something. Three weeks later, he kept teasing me with information about his job, saying something about it, then withholding more info. He finally said that he could explain it better in person, so I asked when I get to see him so he can explain it and he said after Easter. We still talked a bit, but he never mentioned hanging out and he already graduated.
