I'm going to tell a facebook friend to stop tagging me in her relationship posts
Why are you so annoyed that she's tagging you?
It's sickening to read she wants to move in with her boyfriend already -- they've only been together for 6 months!
If she's a close friend, you should be direct with her and respectfully tell her how you feel.
She should make it a private post with limited access instead of tagging everyone.
I couldn't agree more. You need to explain that to her.
