The fact he didnt actually block you does say something, wether that be that he does still like you a bit and so doesnt want to be so harsh as to block you.. or that he actually wants you to know he is ignoring you and not just always offline.
Im terrible for blocking people, I always end up unblocking them even when I know I'll prob just get angry or upset if I talked to them again. Just worried about permenantly losing someone who could become a good friend later on.
