So my advice would be (as I live abroad and have been through it) it is much much much harder than you think it will be. Much harder.
Most ex pats say it takes about seven years before you feel at home and the homesickness stops. Join a Facebook group of Brits in the US for advice.
And yes rhe chocolate is gross. Portions are enormous and fatty is restaurants. Coffee is good if you know where to look.
One of the biggest misconceptions is that because it’s an English speaking country cultures are similar. Wrong. It’s like night and day. Think about it - you won’t know where to get anything. Or who to ask. Different measurement system (imperial) and temp etc. It really isn’t easy.
Americans are friendly Brits are surface polite but won’t go out of their way to speak to you. Americans will. Big socialising with work colleagues isn’t as prevalent. BBQs are a bigger thing.
The crime is immense. The views in the mid west can be non progressive. Guns are everywhere - that isn’t hyperbole.
Healthcare costs are 1000+ per month. That isn’t an exaggeration. Some things are cheaper, some things are mega more expensive - car insurance for example.
Politics are polarising.
Distances are vast - you need to have two cars as Americans drive everywhere - there is no town centre. There are strip malls and malls etc.
Schools are hit and miss but you go to your local school. They make a place for you so choose a house in a good school area.
Holidays start at two weeks a year and can rise to three (if senior) but you usually accrue holiday and then take it - attitudes to holidays are very different. In a lot of cases you have to work a year before being allowed to take a holiday. If you think this will be a bit of an opportunity to explore the US you probably won’t have the time. Internal flights are expensive (like what it would cost to fly home).
You won’t be able to work so think about what that means for you as a SAHM by yourself in a foreign country where you don’t know anyone/
On paper it sounds good but I think you need to do a lot more research. I’m being practical as I think sometimes rhe excitement can take over or current situation overtakes the practicalities or moving.
Every single ex pat I know (every one) has said they are always disappointed by people never visiting (despite all
promises to the contrary when you go). Family expect you to come home.
Sorry OP you couldn’t pay me to move there right now.
I think you really need to think about this and not get rosy eyes about the bigger salary and job etc .
