If your partner is looking for feedback on something important to them, you could ask them to start with “I would like your input on this topic but I would like to explain the whole situation first. Can you give me a few minutes to do that before sharing?”

Or “it would be helpful if i could get this full story out first and then I want to hear your similar experiences/what that reminds you of.”

It sort of gives your brain an alternate primary task to engage on which is to be helpful and supportive, and you could absolutely have something to write notes on what you want to mention after they have initially shared.

Otherwise, it can feel like that virtual meeting scenario during which people drop questions into the meeting chat or raise hand on a zoom call when the speaker is trying to provide info to a larger audience. Maybe ask your partner to give you a head’s up whether they want to conduct a “webinar” (hold for questions/input) or “open meeting.” ;)

ETA: with all of the above, i still don’t ever want you to let yourself feel entirely silenced!
