I sooooo get your FB frustration. I have left my XAH on as a "friend" He never writes stuff like that, but occasionally will comment on post I have made. Stuff like, 'I know, right Honey?"
I f*&**(&NG HATE it when he calls me honey. It actually gives me a physical reaction-like eeeeeeeeewwwwww!
I unfriended him recently, but he threw a fit (we have kids, he wants to see pictures, etc) so I gave in and re-added him. I think I made a point though, he hasn't commented on any of my stuff since.
