Baby shower food argument.

So this coming weekend on Saturday, we are having our baby shower for our baby girl. The party starts at two and ends at five and it is at our home. Now our house is by no means small but is also not huge, and my husband insisted on inviting all of his family which is a ridiculous amount of people. Now, I know half of them won’t show up so I’m expecting about 30 people including our immediate families and friends (a few out of staters on my side and friends from NY. We moved last year to PA). I've already meticulously planned the tables and seating arrangements to best accommodate while also making our house still feel like home as many people will be seeing our house for the first time as well. Now, this is not where the disagreement arises…no the disagreement comes when I told my husband I do not want hot food being served. One of the biggest reasons for this decision on my part is because in Sept. When we had our sons birthday party we had hot food platters setup and it was extremely messy, took up far too much space and made a massive mess afterward which not one person (including my husband) helped clean up. This time I said lets order a few sandwich platters, some crudite platters and a few charcutery type things as well as snacky foods, because we are having activities at the tables and we can keep all that food in the kitchen for people to help themselves to while keeping the mess and stress to a minimum. Now my husband thinks its “embarrassing” to not have “real food”…which in his mind is like lasagna and ribs and stuff…i keep reminding him its not a huge shindig its a baby shower, in our house…and he's pissed off at me for standing my ground with my choice to not have hot foods. Everyone else I've talked to including his mom and sisters agree with me especially because of the time of day the party falls within. He's acting like I said we aren't having food, I never said NO to having food. I just said no hot food, no messy food and I think that he should respect that especially knowing how badly stressed I was last time we had said hot food, he’s making me feel extremely guilty and stressed out about it saying its “embarassing”. I'd never think twice at there not being hot food at a middle of the day baby shower. There will be lots of food, good food and snacks and cocktails and mocktails.…why is this man so stuck on hot food to the point of stressing me to tears?
