One year of knowing each other before marriage is not very long at all and it sounds like it was long distance/you didn’t live together before marrying too so you barely knew each other!
My ex was army so I know the trials of moving due to his career and adjusting to living in a new country too as we spent several years living in Northern Europe and when we first moved there, even though I’d lived there as a child (dad also army) this was a very different experience.
As a child we lived on the base and really only mixed with the other army families, I went to an army school and didn’t need to deal with language or other issues with living in another country as I was still quite young so parents dealt with all that.
As an adult we lived off base due to lack of housing on base so were living within the normal community of those country’s, I had to learn the language (the only one I knew was when we were in Germany I’d learnt a little at school) inc colloquialisms plus quite honestly modern languages are taught very poorly in the Uk and we’re not used to people speaking at normal speed etc - ridiculous really! Plus there are cultural things to learn and ways of how things operate eg the shopping and taxi systems were very different to Uk.
It was a culture shock for us both but I’d say a bit easier for my then husband as he at least had work to occupy him and support his self esteem.
I too am a graduate but due to lack of language and non-transferable qualifications I couldn’t do my normal job there, so my options were limited to the jobs available on base with the civil service and various small Uk retail branches.
I did find a job I loved eventually but it took time, it also took time to settle in and acclimatise.
We were advised by both our sets of parents (both dads ex army) not to visit Uk in first 6 months as the homesickness is just too much and you don’t want to go back, but to give it a chance to settle in and not even call home too often.
They were right.
The first few months were really tough and I had times when I cried and felt it had been a mistake to go with him, but as time went on things got easier, I learned the language, got to know neighbours, got used to how things worked, found my first job (was in a shop so no great shakes career wise but made friends there that I am still in touch with today).
In the end I had a fantastic time and given the opportunity I’d live in any of those countries again like a shot I’d even consider trying a country I’ve not yet lived in if I had the means.
The difficulty here for you is assessing whether it’s culture shock/homesickness, or whether it’s the relationship or a bit of both.
He needs to give you time and space to adjust. He also needs to be pulling his weight at home!
Ok you’re not working right now so fair enough if most of the household chores are down to you I think BUT that doesn’t extend to him not cleaning/tidying up after himself! He’s not a child and you are neither his mother nor his slave. It’s incredibly disrespectful to leave his personal mess for you to clean up.
So you need to tell him this.
Does he treat you fairly in other ways? With money? With affection? Those things tell you if he cares.
And having a baby would be a HUGE mistake this early on. You need to see if the marriage is working first and if emigrating has worked for you, because if there are any doubts throwing a baby into the mix would be a disaster for all concerned.
“I honestly wouldn't give up your flat and close all your businesses until you are 100% sure.” I agree - maybe you can arrange something temporary until you’re sure? A tenant for the flat and someone to run the businesses?
“Everybody was so happy, that finally at the age 38 I got married...” but they’re not having to live it! This is your life you need to be the one happy living it
