I think we basically said the same thing. You can argue that boundaries are for other people but you still can’t control them. Reasonable people/people who care about you will follow them. Others will not. But what you can always do is leave/remove yourself from a situation. Or never put yourself in the situation to begin with. There’s actually a chart in my article from a therapist explaining what a boundary is and what it’s not. And going back to the original article—it was not a boundary for Jonah Hill to tell his ex what to wear and what to post.
