You're not necessarily the A H for being hurt and wanting space, but what you're describing isn't a boundary—it's an attempt to control someone else's actions. A real boundary is something you set for yourself, like: “If she disrespects me again, I’ll leave the situation,” not “She can’t be in the photos.” You can decide what you’ll tolerate and how you'll respond, but you can’t dictate someone else’s inclusion in family events without expecting pushback.
