My teammate asks for honest feedback and then argues with every sentence

My teammate ends every draft review with the same request: “Please be brutally honest.”

Then the debate begins.

If I say the opening is unclear, she explains why it makes sense. If I flag a missing assumption, she tells me the audience already knows it. If I suggest cutting a slide, she spends ten minutes proving that every bullet belongs.

By the end, the draft is usually unchanged and I am exhausted.

She is not rude. She listens, takes notes, and thanks me. The resistance arrives as analysis. Every comment becomes a question she must resolve before accepting it. Sometimes the discussion improves my suggestion. More often, I realize I am now responsible for persuading her that the reaction she requested is valid.

The cost is growing because she asks for review early and often. Last week I spent an hour on a proposal, then another forty minutes defending the same notes in a call. Two days later she sent a new version and asked whether I could “do one last honest pass.”

I have started giving softer feedback to avoid the argument. That is bad for both of us. She receives less useful input, and I become resentful while sounding agreeable.

I tried saying, “You do not have to take every suggestion.” She replied that she wanted to understand my reasoning before deciding. Fair enough—but understanding does not require cross-examining every response until I withdraw it.

I think the review needs a different contract. Before I read, she should name the decision she wants help with. I will give one pass. She can ask clarifying questions, but I will not litigate subjective reactions. If she wants collaborative rewriting, that is a separate working session, not feedback on my own time.

I also need permission to say no when I do not have capacity. Her request for honesty has somehow made declining the review feel unsupportive.

There is a possibility I am part of the problem. I may give too many comments, or present preferences as requirements. A narrower review would help reveal that too. If she asks whether the logic survives without slide six, I can answer that question instead of redesigning the entire deck.

How do you give candid feedback to someone who treats every comment as a debate invitation? What wording preserves the relationship without turning “Can you review this?” into an unlimited obligation to reach agreement?
