I know you're gone, but I'm not sure when I'll have another chance to get on here.
I'm also not sure what option you don't think you have, as I haven't actually suggested anything useful you can do
Sorry, I'm just trying to reframe the argument slightly for you because you will always lose while you allow him to frame it for you. If you think about this issue differently then you might be able to approach it differently.
I don't doubt that he is a good and kind man. But he is a flawed man. Just like all men people ;). Loving him, flaws and all, is not a weakness, and I would never suggest that it was.
"But we are having major problems in this area and he is not prepared to acknowledge any fault here. I could dig my heels in and say "well you are wrong", but then he might walk out on me ... so I would lose, wouldn't I?"
Whoa, whoa, whoa! You think he would walk out on your marriage if you stick up for yourself?
Is that how a lovely guy behaves?
Don't you think he's a big enough guy to take the criticism and learn how to be a better version of him?
Because it doesn't sound like he thinks that, and from the sounds of it, you agree with him.
Both of you seem to be outwardly saying that he is perfect while acting as if he is a childish bully that can't be reasoned with.
How can you change that pattern? How can you let him know that you love him despite his flaws? But that even though you love him there is certain behaviour that you will not accept?
"In an ideal world he would acknowledge some responsibility for the way our discussions deteriorate into arguments. But this isn't an ideal world. He is the way he is. I'm really wanting advice on how I can accommodate this to prevent arguments becoming all-out war."
In a fair and equal relationship he would acknowledge some responsibility for the way your discussions deteriorate. We're not talking Utopia here, just basic respect and adult behaviour.
If all you want is to prevent your arguments becoming all-out war you could keep deferring to him. However, I suspect that if you do that his spiral of self-justification is going to lead you somewhere pretty nasty. You're in what could be quite a destructive pattern of behaviour that has the potential to become abusive.
If you are terrified of him leaving but not prepared to ever go no matter what he does then the power in your relationship is all with him and your problem is much bigger than who shouts and who sulks.
