Absolutely, yes! I don’t really see any tarot card as strictly "good" or "bad" — it’s all about the context and the lesson behind it. The Four of Cups can definitely show up as a positive thing, especially in a spread about emotional boundaries.
I’ve read this card in a bunch of different ways depending on the position, but in your case (as the outcome), it could actually be a sign of growth. Like you’re becoming more aware of how things around you affect you emotionally, and instead of just reacting or saying yes to keep the peace, you’re now taking a step back, thinking things through, and prioritizing your own well-being.
It’s that "pause and reflect" energy — not a bad thing at all, especially when you’re trying to protect your emotional space.
