Go for the friend removal. I was on the receiving end of the un-friend, but I have to admit. It was a GREAT thing for my detachment. I haven't read your whole thread yet, but social media is not your friend in this sitch. If your anything like me you check his page way to much. Does he have a new friend? What did he post? Who is commenting? If you ask yourself these questions. Free yourself from this anguish. Plus he is posting that to Bs to hurt you. Show him you won't sand for that.
