"I could understand that being me"
She wants you to specifically own it
"That would be me"... "I would be like that"
I find using hypthoticals and analogies dont work to well. Likewise my wife wont use hypotheticals to describe a feeling, she states them as facts as applied to her instead. eg "it felt like I was being abused" becomes "I was abused", even though it was a feeling rather than a fact.
You were using an analogy to describe a feeling, she wanted you to state it as a fact. You can't be like something/someone, that is too abstract, you have to say what
you would do
