Keeping it brief. A guy I know ignored 2 messages of mine, which the last one was left unread for over a week. I blocked him after 2 days as I felt upset and annoyed as he did not explain why he was ignoring me. Since then he keeps posting daily things in a communal WhatsApp group I'm part of. I hate fall outs, am I best to unblock him? I have no intention of contacting him but will have to see him a future functions with mutual friends.
