Hey. I moved back to Ireland last year, after 30 years in the UK. It's been tough in many ways, and I still miss my neighbours and friends and the whole support network I'd built up over decades. You do have to put in the work, building new friendships with other adults (easier for kids, for sure). It's like the UK but not like the UK, so there can be a bit of a culture shock. Don't underestimate the need for having new mates. I've finally tracked down a book group that will have me and I feel a lot more welcome now!
But the primary schools are less obsessed with e.g. SATS tests, and to my surprise, my teenage daughter, who has massive anxiety issues, is far happier here. Less pressure. Well. Less constant pressure.
If you're outdoorsy at all, Ireland is fab. Coast, mountains, greenways, hillwalking... We're the most food secure nation in Europe now, good quality local produce, farmers markets (same as the UK - pricy but good for a mooch at the weekends.) Social life can a bit pub-dependent but less so than it was.
Will you get any help with relocation costs or logistics from your husband's new employer when moving? Finding a place to rent, and a place to buy, is an absolute nightmare. We found one rental (admittedly a lovely rental) in over 2 months of looking. Buying.. eek.
Catholic-ethos schools are the default, but there are some non catholic primary schools if that's important to you- Educate Together, for example, or the schools that teach with Irish as the main language (gaelscoileanna). Your kids can still go to a catholic school, if you'd be comfortable with that.
If you are over 35 and you plan to take out private healthcare, do it ASAP, within 7 months of arriving or you get caught with age-based huge surcharges. (Learn from my mistake...)
Do you know anyone else who's moved here? Or do your friends/ friends of friends in the UK know anyone?
Can you get any advice / signposting from the Islamic Centre in Clonskeagh?
Moving somewhere you don't want to be can be stressful - our move was the right decision for us and very much what we all wanted but I still found it stressful. Good luck.
