How can I protect a family member without making things worse?

I’d start with the parts that can directly reduce the pressure: ask what support your aunt actually wants, help her keep records of concerning interactions or financial issues, and look into appropriate local support if she’s open to it. Try not to take over decisions for her, even with good intentions.

If you also do spiritual work, you could make it focused on her safety, steadiness, and clear boundaries rather than trying to control or punish someone. That keeps the practice aligned with helping her, and doesn’t depend on promising that a ritual will change his behavior.

For a spiritual approach, I’d keep it simple and protective. Set a clear intention for your aunt’s well-being, use a practice from a tradition you understand, and take ordinary precautions you already trust. If the working involves another person, consider whether your aunt would be comfortable with you doing it on her behalf.

I’d be wary of anyone who says there’s one guaranteed method or that you need to pay for special materials to make it work. You can research through reputable books or practitioners who explain their approach without pressuring you.

Since you’re unsure about baneful work, that hesitation is worth listening to. Retaliation can bring more stress or conflict, especially when the situation already involves family and money. You can choose not to hex and still take the situation seriously.

A protective ritual can be a way to focus your own intentions, but it can’t replace practical help or your aunt’s choices. If you do anything, avoid actions that could expose her, violate her privacy, or make decisions on her behalf without consent.
