Good luck with setting up counseling margo.
I know your IA isn't a dinner specific thing, but overall general communication stuff.
But, for us, dinner is a funny topic too.
My husband is a go with the flow for dinner kind of guy.
Usually the conversation goes
Me: "What do you want for dinner?"
J: "I dunno, what do you want?"
Me: "I dunno, any cravings?"
J: "Not really"
Me: "Veg, fish, meat?"
J: "All are fine".
Me: "How about we have X, Y, Z"
J: "Sounds great!"
I do throw it on him sometimes, because he cooks for me a few nights of the week when I'm out having fun. Not that he can have dairy, but he's luckily not a cheese on toast, beans on toast, etc kind of guy. He's more a I'll make either pasta, fish 'n' chips, pizza, or curry kind of guy.
