Help! blocked friend's posts! Can't get tagged!

hi!

Okay. So you know how annoying facebook friends can get. Well, I blocked someone's nagging posts (he's in the family), and now I learn that he can't tag me in a post! I'm just missing from his list when he types my name in (@name) like we're not friends. He asked me if I had blocked him or something. I said noooo. I blamed facebook being stupid. Anywho! I go to his profile page and make sure we're friends AND that I'm following him. He writes on his post how weird this is, and I'm slowly dyiing.

When I visit his page and click on the arrow of one of his posts it says "I don't like this." There is no undo block choice. Any idea? (I want to avoid unfriending and refriending)

Update: I have also checked "view all blocked users" and there isn't anyone on the list. I remember choosing "hide all posts" on a facebook post. That's all.

Thanks!
