I accidentally declined a message request instead of reading it on facebook messenger. Will the person know I declined it?

Will he see if it was seen? Will he still be able to send me future messages? I want to reply to him but I cannot find him anywhere.

"Will the person know I declined it?"
— No. The person wouldn't be notified that you've declined it.

"Will he see if it was seen?"
— No. He wouldn't know that you've seen if you decline.

"Will he still be able to send me future messages?"
— Yes. If he messages you again, the "Accept" and "Decline" will appear again.

go to his page and send him a message saying you fat fingered his request , once you send him a message request his peevious message should pop back up if not you have already explained what happened... its called a redo on both of your parts... gl
