I edited my post because I realized I wrote triggered. I'm about to rewrite essentially the same thing, but I do not think I've triggered. Go figure.

You write of anger. That's pain - not the only emotional pain, but it's one of them. I'll suggest you're still dealing with pain from the way you ended your relationship with XGF.
I believe your words - in your profile, for example - show passivity and avoidance. From what you write, you never confronted your big questions that only your XGF can answer/could have answered. You don't know if your XGF actually cheated, though what you do know is pretty - but not definitely - damning. You write that you suggested splitting as a way of getting your XGF to talk about your relationship, and when that didn't work, you let her go without raising the issue yourself.
You do not write in a way that indicates you have addressed your passivity. Instead, you write about WSes and your principles. IMO, you are protecting yourself against some sort of pain. I know what kept me passive about my relationship with W2b, so I know one thing that might have kept you passive, but that's only one possibility. I didn't discuss the relationship until I realized she was as into me in her way as I was into her in mine. My reason for not discussing it was that I feared rejection. Again, that's me. You're the only one who knows why you let your XGF go without getting the facts you needed.
But you write that you did let her go while wanting to discuss the relationship without even trying to get the discussion you wanted. That's both passive and avoidant. My bet is that still hurts. You haven't written anything that says you've taken responsibility for that, and IMO, that's a problem for you.

You raise theoretical question after theoretical question. That doesn't help anywhere near as much as sharing experience and how the experience affected oneself. Theory distances a person from their pain. That's avoidance.
I'm convinced healing comes faster and goes deeper when a person confronts the pain directly. You say you're not as healed as you can be. Actually, you're as healed as you're willing to be.
My bet is that confronting yourself will allow you to release the pain of passivity and make your thinking clearer and your life easier. But you're the one who has to choose to do te work (and do it).

The above is based on my reading of what you write. I'd say that you think I misread you purposely because you're not reading yourself correctly - or you're not sharing some important stuff.
Obviously we're all a lot more than what we share on SI. IOW, I'm hoping these words are read to say that you paint yourself as passive and avoidant with your XGF, and I understand - and hope all readers understand - that's different from saying that you are passive or avoidant in any other area of your life. Further, your writing might have omitted something that invalidates my reading of your posts.
So I could be wrong. But i think I've identified a pattern in you.

Thank you for answering my questions.

I did not eat any sandwich at all with regard to R(econciling), and I never thought I did. I'm not alone in that.
Per my W, and per my involvement in SI since 2011, I see myself and the vast majority of BSes as collateral damage. My W did nothing to me directly. That's what I think 'the A is about the WS, not the BS' means, and I agree. My W fucked up; I didn't.
Every BS has a free choice between D, R, and staying without full R for any reason they think sufficient. I DID have to accept that my W had sex with someone else, but I've always thought her body is hers, not mine, and I never wanted to control her.
Now that I think of it, I've always wanted her to be with me voluntarily, but one of the reasons I stayed was out of duty, because of the M vows. That seems asymmetrical.
OTOH,my W helped me immensely during some very dark times for me. Maybe I stayed for her because she was going through a very dark time for her. Maybe I really had a debt to her, and staying was a way of repaying it.
Mainly, though, I think I'm a better me with her than without her, and I thought I wanted to spend the rest of my life with her. IOW, I thought R was my best option. So far, it has been a good one.
But my main point is that I entered R freely. No one made me stay. No sandwich was involved.
Some people think there must be a sandwich. That's wrong.
Some people think R would be a disgusting sandwich for them. I expect they're right - for themselves.
