Hi, Brandi! Long time no see (chat?!!).
The way I interpreted your original post is that your DH is in a bit of a cranky nitpicking mood and the current thing he's found to nitpick about is FB. I took it as FB not being the real issue, but him being stressed and needing to let off some steam and it's being directed at you, because....well, you're there. Did I read it correctly?
If so, I totally get where you're coming from. Both DH and I do that to each other sometimes. We try not, but it does happen from time to time. I feel like an a$$ when I do it to him. (Ok, so maybe I'm not perfect, but don't tell him I said that.

) I can't even imagine spending 24/7 with him, either. I adore him, but I don't think he and I could ever work together.
From all the other things you've posted about him he sounds like a great guy, so I'm sure it will pass soon (if it hasn't happened already). Hang in there.
