DH and I have recently realised that we need to make a very significant move to another country. It's the best/inevitable choice for a bunch of reasons. We used to live there and know it very well. I need to be close to a family member who is in very poor health. DC will grow up with cousins the same age. We will be able to afford a lovely house with a big garden. It will be a big step-up for me careerwise, and DH will no longer have a horrendous 1.5hr commute which I'm afraid is damaging his health. Heck, even the air pollution is lower - in every respect it will be a much better quality of life for us.
So it's a no-brainer, right? There's just one problem I can't get over. We love the school the DC attend. We did the OTT MN thing of visiting a million schools and putting a ludicrous amount of thought and effort into selecting the right school (I mention this because I suspect I have some cognitive bias/choice-supportive bias going on here).
I don't want to get too into why exactly we love this school, because I don't want to be convinced that the stuff we love about it doesn't actually matter (be it single sex vs mixed sex, Welsh language medium, academically selective, religious etc etc). The problem is that the things we love just aren't available, at all, in the new country.
(For example, say we love that it doesn't have a uniform, and it's single sex - every school without exception where we'd be going is mixed sex with strict uniforms.)
I am being vague because I don't want to trigger a bunfight about how great/awful Catholic Welsh-language all-boys schools are 
. It doesn't matter what the specifics are, the issue I have to overcome is the emotional difficulty of letting go of stuff I've put so much effort and time into prioritising (and which seems to be making my DC so happy). I have to come to terms with the fact that if we go ahead with the move, they just can't have some of the stuff I thought was important.
And that's really hard to get my head around.
I guess it's partly that I've been telling myself that education is the most important thing for so long. I'm not sure if I entirely believe it or not. I guess I don't if I'm prepared to prioritise all the other stuff I mentioned in my first paragraph (time with family including DH, quality of life etc) above The Perfect School. And as I type this I realise the perfect school doesn't really exist.
There would be a few, less-important-IMO benefits of the new school system above the present one? Should I focus on that? Or would that distract me from the important Unclenching I need to achieve ?
[Should have mentioned - the DC are young primary school age.]
