To follow what I want? (Long - sorry)

[WishIwasanastronaut]

Hello. I post periodically (usually when I'm pissed/kids are with their dad/I reach rock bottom).
Anyway, I have been reading with interest a recent post about whether you should always act in the best interests of the DCs and now I'm doing my own head in...
Background (don't want to drop feed)...
I live in a Northern European country with 2 bilingual D.C. (6&9) who are at local school. Ex DP was abusive although we have a superficially 'good' relationship since he went.
I own a nice house that needs work but will continue to increase in value in the country I live in. I get by in the local language but work in an international school.
I DONT REALLY LIKE IT HERE.
I don't admit this to my work, my friends or my kids.
I AM NOT CHALLENGED IN MY JOB
I KNOW I COULD BE MUCH HAPPIER/DO A LIT BETTER CAREER WISE SOMEWHERE ELSE.
But I am kind of OK just ticking over.
Fucking thousands of great jobs all over the world and back in UK right now.
My DCs are happy here. They were born here and their dad is here.
I am not really unhappy. But I dont go out much or really feel secure/happy. I just know I could find better (mentally and financially) elsewhere.
My lawyer said that I would almost certainly win the case to take the DCs away (but it would go to court and therefore fuck up the relationship I have with their dad).
AIBU to myself to sit it out for a few years or AIBU to my family for deciding to go?
Thanks for reading and sorry it's looooong!

You do realise that your children will grow up and leave eventually? Why can't you just wait and then do what you want when it won't effect them?

Yeah that was exactly my plan. It will mean my career and finances wouldn't be as good as they would if I moved now.
It was that other thread that made me think 'fuck it, why hang around in a place I don't want to be for another 15 years?'!!!

Is there nothing challenging you can do where you are now?

Possibly a start up but as a SP of pretty young and needy kids, I dint have a lot of time (or money)...
