Welcome to the thread Spike!
"the relationship between Rhett and scarlett at present is pretty poisonous.". Lol, that seems to be their normal and it sort of spices it, I think. I don´t remember the story so well as to remember about the misunderstandings, Spike, but their recurrence is significant. I fully agree with that;" Each feeling rejected and withdrawing. Each withdrawal feeding the rejection felt by the other."
Sometimes it seems to be rather a war of power than a war of love between the two. Or maybe their love can´t exist without this power challenge.
