I'm going to try to be as succinct as possible....
DH from country A, me from country B. DC born and raised in country A (DH's) until age 10 and 8 then we moved to country B (mine). We've now lived in country B - England - for 2 years.
We're trying to decide whether to remain in England or return to country A where DH/DC born.
In country A we had a bigger house but quite remote. In England we can't buy a house in the area we live (still own a house in country A that is rented out) for the foreseeable future so we'll continue to rent long term.
In country A we had a higher income but much greater expenses and less amenities. Probably evens out in the end.
In country A education is very good but DC1 is in a super-selective grammar school here with excellent results and wants to be a doctor. DC2 may not get a place in the same school but the other schools here are very good.
DH hates his job here and his old employer in country A would welcome him back with open arms!
My life is tons better here - I never felt truly accepted in country A, or rather in the area we lived. The availability of amenities and better service has a huge impact on my day to day life here.
In country A and B we are not near our families - both 1.5 hours journey away.
DC are not unhappy here - lots of friends, activities etc. - and have never outright asked to go back to country A but say they miss their home and the countryside. What is bringing this matter to a head is that both have expressed that they feel that there's something that doesn't quite click here, although they feel welcomed and happy day to day.... and DH loathing his job here.
I feel that there are better opportunities for DC in England both in terms of education and future careers etc and amenities are so much better where we live now. But the trade off is less space and not being able to buy a house/DC not feeling like it is their real home.
Hmmm sorry for the length but I didn't want to drip feed and would be SO so grateful if anyone has faced similar and could advise how they approached such a decision.
