The right people hear your boundary, say “got it,” and keep treating you the same. That’s how you know they’re right.

Saying no is a test you did not intend to set. Someone who accepts it without a negotiation, without going cold, without making you pay for it later, has shown you that the relationship was never resting on your compliance. The ones who escalate have shown you something too, which is uncomfortable but useful.

Watch what happens in the two weeks after you say no to something. Notice whether the warmth stays the same, because that is the real answer rather than anything said in the moment. And when someone sets a limit with you, accept it and do not go quiet.
