How to bring it up with wife

I'm a husband, looking to bring it up with my wife (we're both mid-30's) to give this whole thing a try. I do better than a solid chunk of men, I'd say, but totally not enough, even more glaringly after getting the card deck and just running through what cards each of us hold already, by myself. All the guidance I see is how to get your husband's buy in.

I already have my buy in, obviously. And she'll FOR SURE join. But I'm hoping that the first sit-down isn't this "hey, look at all this shit you do." And her get flustered.

Basically, how would you want to be approached by your husband for this? I've listened to the audiobook, got the deck of cards, watched the documentary. I know how to lead it. I'm not bringing her a project to kick off for me. Out of the blue? "Hey, can I get an hour of your time tonight to discuss our workloads?" I'm all ears.
