How do you know if someone blocked you off on kik?

So i was talking to this guy on kik and I sent him a message before and it had "D" beside it and he never read it but I sent a a new message after that and i'm pretty sure it said "D" beside it but in the morning I checked kik again and it changed to "S" so did he block me or what?

The status of sent messages are not reversible. You must have misread the "D". Hint: You can read them "R" without it showing such, just by viewing it in the status bar and not opening it.
