UK, Ireland /
Irish (live in London) moving to Poland [44]
with a right wing authoritarian government
No... not really, it's a neo-PRL system of patronage and petty dishonesty and corruption where for the government connections count more than competence ---- but they're not jailing opponents or censoring the press, there are no violent crackdowns, in other words there are none of the things a normal person would expect from a real right wing authoritarian government. It's tawdry and embarrassing but not a real challenge to democracy (at least not yet).
I also had no idea you actually dislike living here.... maybe you need to move somewhere that you and hubby can both be happier... he didn't like the UK or Ireland?
moving to Poland, not speaking the language etc
Poland is not a user friendly country and your wife is unlikely to fully realize how alien and confusing things will be.... (depending on how long she's been in the UK she's liable to be having her own readjustment issues and won't necessarily be as helpful as either of you might like).
And... be aware that successful adjustment to Polish realities will absolutely depend on your ability to be assertive (not a general strength for English speakers ime). Arguing with people is not something people avoid and if you try to just get along you'll end up with footprints on your forehead....
Poland can be a great place to live if you can adapt, which includes not just the language (non-negotiable for longer term residents) but also lots of cultural issues. If you expect things to be like the UK (and or want to wait the country out to become more like the UK) then... it's not for you.
