what would you do 72 years old farmers wife

Your husband is a selfish man. You're telling him you don't have everything you need and he's saying he has everything he needs so it's fine, end of discussion.

Agree with others, do something for yourself, don't have regrets but equally don't make somebody who has no interest come with you - they'll hate it and you'll have a bad time! Have you thought about doing something like this? https://www.berryscoaches.co.uk/day-tours/events-attractions/

If you can’t drive then learn. Then drive to the seaside.

I don't know if your circunstances are difficult (are you needed on the farm every day (no one to cover for you), is your huband being difficult about you going on your own...?) but if there are no major issues, just do it. My dad doesn't like to travel anymore so in the past 10 years my mum has been all over the place with friends and groups. She's 81 now and was in Morocco a few months ago and is off to Romania very soon. Take your chance.

Book something and go! You don't need your husband's company or his permission! 100 miles is not far - you'll be there in a couple of hours.

OP it would help to say where you were and whether you have access to money to be able to take yourself off somewhere. If you are in the US you have a variety of oceans to choose from and at least you don't have to worry about passports and visas. Just put one foot forward and get the ball rolling.

@farmerwifesfriend , are you a friend to the farmer's wife?
Will you travel with your friend?
Are you concerned about her? Her marriage?

Go on a singles holiday for over 60s!
Saga is popular but there's loads of them.

My gran aunts go all the time. Thet are fully organsied with lots of sightseeing and activities (tours, cooking classes museums, art galleries, cocktail classes, (interesting) factory tours etc )heres now a little gang as they made friends with other women over the years on diff trips. Occasionally the husbands come but often its just "the girls"

You could also just book a place on the coast and treat a friend!

Put a few meals in the freezer and order an online shop (if you need to) for dh while away
Farmer life is long hours

Divorce?

The OP appears to be in the US where it is not uncommon for people to not leave the State they live in.
80% of Americans have never had a passport.

I don't know where you are, but over here there's a thing called Rory's Travel Club - they started out just doing cheap trips, but now they do all sorts of things, including group trips which welcome lone travellers, so you've got support around you.

I've not done them alone, but I did a similar thing on a lapland trip with the kids - got a full bundle so I didn't have to worry about organising anything, we just turned up where we were told and got on a coach - it made the whole trip so easy.

If you wanted to start out small, I bet there's a coach company relatively local to you who does day trips to various places, get your arm in on those, then you can head out further if you find you like it.

It’s time to plan your adventure to the ocean and other places. You have one life.

You need the sea in your life. Do you have any children you could go with?

Doesn't he allow you to go away by yourself?
If he doesn't, well you have a problem DH.
If he does, well, organise a solo break or get a friend to go
Are you in America?

Is he still farming? What does he farm? If he’s a livestock farmer, it’s true that he can’t leave regularly or take a holiday without it being a major inconvenience. My friend’s dad is a dairy farmer and he felt awful asking someone to cover for him on my friend’s wedding day, nevermind for a holiday.

It’s a shame he’s never done it for you though. At this point, he’s very unlikely to change. I’d be looking at going by yourself or with friends.

Go on your own. Be independent. He's happy where he is so there's no point in forcing him.

My farming wives all holiday alone or with friends.

Go without him, or go with a friend. My parents are 90 miles away, and I visit them for an overnight stay with my child every week during the school holidays. It really isn't that far. My husband stays at home and gets some work done while it's quiet! I understand that this may be something you would prefer to do with your husband, but I believe it's better to do it without him than not at all.
I'm assuming you're American (nowhere in the UK is more than 87 miles from the sea) so be prepared for a lot of incredulous replies here. Brits travel a LOT. But actually that just shows how easy it can be, especially in the internet age. I'd book a proper hotel if you're not a confident traveler, then the desk clerk can help you if you need assistance with transport links, local knowledge etc. while you're away.

Are you a72 wife or is the farmer 72?
Is this a new relationship for you?

I’m in uk and our nearest seaside is about 95 miles away, so if I was referring to how far I’d say about 100 miles

I don’t understand this, you’re using typical North American terms and yet if you’re located there 100 miles can be a drive to the nearest Walmart. 100 miles in Australia is also no distance, although you use miles and not km?

The OP must be north American. No 72 year old Brit would call the seaside and holiday "the ocean" and "vacation".
Also, it's not uncommon in the US for people to have never left their state, especially the older generations. Can understand that farming is very restrictive.

If you're not confident to go on your own and money isn't an issue, there are companies that organise tours you could join.

You will meet new people who have similar interests to you and have a lovely time! Leave your husband at home.

Don't sit there wishing you could do something, do something about it and go to see the ocean!

That's sad. I am only 32 but would come to the beach with you if you are close to the South East UK, I can bring my nan she is 74 if you'd like. We only get one life, please don't spend the rest of it in a bubble if you have dreams get out there!
