Am I still blocked on my friend's iPhone?

I got my friend mad and he blocked me. I know because my calls went straight to voicemail and texts was first blue (iMessage) and it didn't say delivered on the bottom. Then minutes later the texts all sent as SMS (green). I used another form of social media to contact him. I saw he read that message. So I called him and he picked up. He was still mad and said he doesn't want to talk to me right now. Throughout the day I have been checking the text messages and noticed the arrow to send text messages was still green until a day later the send arrow turned blue. Does that mean I'm unblocked or still blocked? I don't want to call or send a text because I don't want him to think I'm annoying.

If it's green, it's possible that he blocked you. I do know that if it's blue, but the delivered notification doesn't show up, you're blocked. Keep in mind, the "send message" arrow will remain the color from your previous messsage. It only checks until you actually send one. And hey, kill some time and don't think about it too much.

When someone doesn't want to hear from you,
the worst thing you can do is force that person to listen to (or read) what you say.

Back off for at least a month.
Let it go.
