Setting Boundaries With Family
How to say no to people you have no intention of losing.
By Daniel Reeve · 7 min read

A boundary is about you
Boundaries are not rules for other people's behaviour; they are decisions about what you will do. 'You can't comment on my weight' is a demand. 'I'll change the subject when that comes up' is a boundary you can keep.
That distinction removes most of the conflict, because it needs nobody's agreement.
Say it once, plainly, early
Choose a calm moment rather than the middle of a holiday dinner. Be brief and warm, state the limit and the reason once, then stop explaining. Over-justifying invites negotiation.
Expect discomfort. A boundary that pleases everyone immediately was probably not needed.
Hold it consistently
The first few times will feel harsh; consistency is what eventually makes it unremarkable. Follow through on the action you named — leave at the time you said, decline the call, change the subject.
Boundaries protect relationships more often than they end them. Most resentment comes from limits never stated.
