I've lived in big cities, large towns, villages and a remote rural hamlet.
I preferred the Hamlet but DH felt the need for a bit more infrastructure.
Country living is isolated, slow, smells a lot even without muck spreading, has properly difficult driving all year round, for a wide variety of reasons. Your electricity can be hit and miss, mobile phone signal and internet too. You may not get gas, fuel oil tanks are not pretty and smell, septic tanks are an eye opener too. Log/ coal fires are great, until you run out of fuel, clearing the grate, the dust is a pain, lighting the bloody thing an art in itself. Cows, combines, tractors, the milk lorry, the fuel oil lorry, the shit lorry. Ramblers with upside down maps eyeing your garden, hunt sabs spitting at you just cos you live their, badger saviours too.
Noises! Fox or tortured baby? Screeching banshee or Randy hedgehog? Burgler with a smoker's cough or sheep? All can be terrifying.
And many things that are perfectly normal to the majority of people are rare occurrences, weird little things, foodstuff, deliveries, pavements, street lights, night life, most forms of entertainment... all rationed or non existent.
I've had a few city escapees as neighbours and most have enjoyed 4 or 5 years and then started to feel too isolated, retirement starts to look lonely, the house and garden like hard work.
They are as out of their element as many farmers transplanted to a city... and I know a few of those too!
It's not snobbery, nasty etc to advise, generally, that you won't like it out here in the boonies. It's just that many of us have watched a lot of houses modernised, gardens landscaped, 4x4s bought and wellies tried on only for the excited family to hate the weather, flies, smell, lack of just about everything they hadn't even thought of, the isolation, dirt - oh the dirt, remind me to tell you about the 2 GPs who were driven to hysteria by the dirt, literally!
It isn't just a house in the country with shops miles away. It is an utterly different way of life. I love it. There are as many friendly, beautiful things as there are bad. But it is ALL very different.
Rent for a year before you make the change permanently. But don't be affronted by posters who laugh, it's usually a wry laugh, based on observation and trying to help others understand what it is they are experiencing.
