To think you should eat outside in summer

YABU. His preference to not eat outside is not less valid than your preference to eat outside.
I hate eating outside. I don't find it enjoyable or relaxing. Insects (even one or two), too warm/too cool/too bright/too breezy etc is all just uncomfortable and I'd rather eat inside. I don't want to spend the whole time on edge about whether a wasp has crawled into my drink whatever.

I'm like you op...I'd rather eat outside...yes wasps a flies are a bit of a pain, but it feels a bit miserable to be sat indoors when you're on holiday

I hate eating outside. I get eaten alive by insects!

Well obviously it's a personal choice/preference, but as a family we almost always eat outside on a summer holiday, and in fact we've had most of our meals outside at home this year since Spring! I love eating outside and so does my DH. The kids are ambivalent and will often take their lunch/breakfast inside instead. For dinner they don't get a choice!

It's obviously nicer to eat together as a family though, so I think it would be nice if your DH would compromise a bit and have at least some meals outside. Is there a better time of day for eating outside? Could you get a wasp catcher? And no tv!!

Exactly.

YANBU.
Where is the middle ground? Will he never join you outside? So you are forced to have to eat inside if you want company or sit outside alone? And not surprising that a child gravitates towards a TV screen, so she is following him inside.

The image you have in your head of all eating outside together and having a lovely time will never happen because he doesn’t like eating outside, so you need to let it go. It’s not a hill to die on.
No excuse for them having the TV on though

Dinner for me, a blood buffet for the midgies.

I hate eating outside. I wouldn't be pleased if my partner tried telling me where I should or shouldn't eat.

I detest eating outside. I don't want bugs buzzing around me food.

I don't think he's unreasonable to not want to eat outside. I do think it's weird to barbeque food and then take it inside to eat though.

No. It would be awful because the only way you'd achieve it is under duress. And your H would be fussing and moaning, swatting at imaginary flies and generally making a big negative passive aggressive kerfuffle out if it. I'd rather read my book in all honesty.
What would be nice is if you all WANTED to eat outside.

We must be married to the same man 😆

My OH is also a nightmare in the house with flies, he wants all the windows and doors shut even in beautiful weather. Really annoys me!

But in relation to your OP, there's no point in him sitting out if he isnt going to enjoy his food.

People should do what they want to do.

Sit outside, if you want to do that.

Sit inside, if you want to do that.

There is no “unreasonable”.

Yanbu to want to eat outside
YABU to think others should sit outside to eat just because you enjoy it

I don't like eating outside. Some people don't.
If it's your bag then just crack on.

They don’t share your spirit OP.

Many of us love to be outside as much as possible, it keeps our spirits up and is the summer / holiday / outdoor vibe.

I love eating outside in winter, too, a flask and sandwich on a winter walk.

So I sympathise.

Are you away? When / if at home invite some of your girlfriends to come over for drinks, and sit outside.

I would not be impressed that he is encouraging your Dd to eat in front of the TV when on holiday.

We eat outside every opportunity we get, and that's not abroad either! As OP says there's plenty of time 9 months of the year to sit inside in a cave and watch the rain run down the windows.

Maybe you could compromise, and have lunch inside but all go outside for after dinner coffee/drinks/water whatever and enjoy that.

YANBU in my opinion.
I LOVE eating outside. If it's warm enough I'm outside. My DH is also not a big fan of eating outside, but will do so if I say we are eating outside.
It's the same if we are eating out in the summer, if the weather is warm enough I want to sit outside. I will look for a place that has available outside seating as that's part of the enjoyment for me when eating out in the summer.
Like you say, there's many many more months eating inside in the UK.

"it's a shame not to" is just another way of saying you want to, but with an extra helping of "and everyone else should want to too". They don't, tough!

Personally I like the idea of eating outside much more than the reality. You say there aren't many wasps, etc., but it only takes one to ruin the whole experience. It's much easier to be outside when you're not eating, because then you're not attracting insects so much!

Sorry im with your husband, i hate eating outside. Bugs and flies annoy me and then one gust of wind and something goes flying off.

So go and sit inside with them.

There's no "should" to this. Why do you think there's a right or wrong about whether someone finds something comfortable/enjoyable or not? You can't dictate other people's opinions.

I like to eat outside but dh doesn’t, he’s always bothered by seagulls lurking so can’t enjoy his meal. I just have to accept that and eat alone or inside.
