First, I would unfollow her. Then I would wait a month or two. Then I would unfriend her. Or put her in a category that does not have full access to your facebook posts.

You eliminate a lot of stress just by unfollowing people on facebook. That's what I've found anyway. They stop buzzing around inside your head, and you firget about them. Eventually, I believe they decide to unfollow you. That gets you where you want to be.

Considering how much personal stuff is on facebook, I don't get why anyone wants to be friends with anyone other than family and real genuine friends. Or avail yourself of the option to put those you really want to be connected with inside if a designated group that are the only ones who see most of what you post.
