You don’t need to explain yourself. Others need to learn to respect your choices about yourself. Yes, it’s tiring. It’s their fault, but partly your problem.

Your responsibility ends with “Thank you, but no.” Unfortunately, some people will feel hurt by this. You can’t change this; only they can choose to interpret your response differently. And most people never try this.

If you want to establish your boundaries, then you need to practise letting them feel hurt and not feeling responsible for it. This is one reason I meditate.

Peace.
