I sent a message on messenger before it delivered them I blocked the person?

So I sent a message to a friend on messenger, but before it could deliver I blocked fhem. But I unblocked them and it still says sent. I blocked them out of fear bc I thought it would deliver. I had him blocked since May of this year and yesterday I unblocked him but blocked him back. Will the message deliver or... show more So I sent a message to a friend on messenger, but before it could deliver I blocked fhem. But I unblocked them and it still says sent.

Will the message deliver or did it get lost due to the fact I did block him before he could get it?
