How do I manifest a specific outcome when I don’t want to participate in the situation at all?

I’m looking for manifestation advice because I genuinely don’t know how to approach this without getting mentally exhausted by it.

There’s a “he said/she said” type of situation involving me that originally happened almost a month ago. I thought it was over, but today it has been brought up again, and I really, REALLY don’t want to participate in another confrontation or discussion about it.

To make the situation clear:

• Friend A is friends with both me and Friend B.
• Friend B and I have NEVER directly talked. Anything between us has always been through Friend A.
• Friend B is actually closer to Friend A than I am.
• Today, Friend B texted Friend A saying that she wants to call and talk about the situation.
• Friend A told me about the message and said something along the lines of, “Let’s see what she says.”
• I didn’t ask for details because I don’t feel like I’m in a position to interrogate Friend A about it, especially since Friend B is closer to them.

The problem is that ever since hearing about this, I’ve become anxious because I do not want to be involved in this anymore.

I don’t want another confrontation.
I don’t want to explain myself again.
I don’t want people discussing me or asking me to participate.
I just want this entire thing to resolve peacefully and disappear from my life.

I’m specifically interested in manifestation because I want to manifest the outcome, rather than trying to control what anyone else says or does.

So if you practice manifestation, how would you approach this?

Would you focus on something like:

“This situation resolves peacefully and completely in my favor, without me having to participate in any confrontation.”

Or would you focus more generally on:
“I am completely uninvolved in this situation. Everything resolves itself peacefully, and remain unaffected.”

I’m also struggling with the anxiety of the 3D situation because I obviously don’t know what Friend B is going to say to Friend A. I keep thinking about possible scenarios even though nothing has actually happened yet.

I would really appreciate advice from people who have successfully manifested a specific outcome in an interpersonal situation, especially when you didn’t want to take action or participate yourself.

How would you persist without constantly checking the 3D or worrying about what might happen?
