IMO, the stay/go decision is not logical. It's emotional, and emotional logic does not follow the rules of scientifi method. For example:
I haven’t changed my belief that staying with her would eliminate my own self-respect.
OK. That's that, then.
OTOH, it's unwise to let someone else control your self-respect. In fact, you and only you are in charge of your self-respect, even though it's often difficult to keep that in mind.
I am/was really committed to her and remain so but her complete lack of any regard for me, and to a lesser extent our children, for such a long time, through so many good times and bad, with so many chances to end it and clear the air with me, has made me realize she never wanted this on some level.
My W cheated in part because she didn't feel lovable or loving. She cheated out of self-hate and despair. Her A was due to her own issues. I was collateral damage.
So not having regard for me was not a potential cause for D for me. Your W may be similar. What if she is?
You can D or R whether she did or didn't respect you during her A. What matters is whether or not she will respect you for the rest of her life - I wouldn't R unless I thought my WS would come to respect me pretty quickly.
Despite her saying that she wants to remain married, I’m not really feeling that to be the truth.
Now THAT is critically important. If you think she just wants comfort out of staying M to you, you have a terrific reason for D and against R. Of course, you might be misreading her, right, and what if you are?
Your belief she doesn't want to be M to you may actually be your signal to yourself that you don't want to be M to her.
IOW, you can make any action by your WS or yourself as a logical reason for D and/or R.
Here's my point:
After d-day, the BS (and WS, too) make their own rules about what to do with the relationship and how to choose. You make rules for yourself here.
I know choosing to stay or go is difficult. It's probably one of the most difficult decisions a person has to make.
The decision isn't about what your W did in the past. Choosing what to do with your M is about the future. Logic doesn't take you very far into the future - there are too many inter-dependent variables to be able to predict much.
And yet, you have to predict what your life will be if you D ... or R. Since you know yourself better than anyone else does, you've got the power, bro.
There may be multiple good answers for you. Just don't depend on someone else - or even someone in your head - to make the decision for you.

WRT proportionality:
At first I speculated about how I'd be responding if my W's A had been an ONS, or multiple years, or if she had more than one ap, or if the ap had been male, or if it were 'just' an EA. In the end, I decided all of the above would have been devastating. If she had kissed someone else in a way similar to the way we kissed, I'd have been devastated. If she had shared a secret between us with a friend, I might be devastated. You know why I haven't cheated? It's because I know the consequences would be devastating, and I knew that when I was 16.
I would argue that proportionality does not apply to relationships and actions that are supposed to be loving. Proportionality has at best limited utility when dealing with human responses to events, especially to traumatic events.
I know a long term A is quantitatively worse than a(n) ONS, but affairs have dimensions other than and often more important than quantitative.

My W cheated in part because she didn't feel lovable or loving. I've always known I chose R for healthy and unhealthy reasons. This is one of the unhealthy ones. I just said that I stayed because I let her hook me into the Rescuer role in a Drama Triangle. Wow. I never saw that as clearly as I do right now. Ah, well. Live and learn. I'll think about this, but I doubt it will make me change my mind about choosing R.
