@pearl ugh, 'deck' is the worst. It's a powerpoint, or a presentation if you don't want to use the software name, but it certainly isn't a deck. That one always gets my back up.
This is exactly what we do in my house, and it's taken us from the brink of constant arguments about money, to sensible, healthy conversations about money. We pay a proportionate amount into a shared bills account for all the bills and household expenses, keeping our own day to day spending separate, and every month sit down with all our statements and note down where we're at in a big spreadsheet. We don't keep track of all our purchases, but just noting down snapshots is enough to keep us aware of where we're at, and also not at one anothers throats! And definitely, definitely never do money talks hungry, tired, drunk, or otherwise overly emotional - make them neutral spaces and call them off if it starts getting too heated. Nothing good comes from that!
