Hi, not suprised he is bored and lonely, he needs to get himself invited onto one of the expat compounds and he will have a bit of a social life.
Yes, freedom can be an issue but if its what is best for you as a family, you can work around it.
Totally understand your comments ref schooling. DCs 1 and 2 were at an excellent prep school in Sussex before we came out here and I have to say, the british school here is not a patch on that. We took the decision to send DD (13 in 5 days as she keeps reminding me daily by email) back to the UK last year as she wasn't doing as well out here. DS1 was effectively stuck here as halfway through his GCSE course but thank god he will be finished those in a few years then back to the UK to a private 6th form.
How old are your DC? if they are younger than my eldest two (youngest are 2 1/2 and 4 months) then if you are planning on only a few years and being back in the UK before they are aged either 11 or 13 (depending on schools in your area as some private take at 11, some at 13) then that would be ok. I certainly wouldn't recommend Saudi for teenagers, far too restrictive for them.
Ref summers, most of us sensible ex pats bugger off at the end of June/beginning of July until end Aug/beg Sept. I was due to leave KSA end of June but had to bring it forward to next week due to family circumstances. Its far to hot here. An hour ago (12 o'clock KSA time) it was 49 degrees which is stupid.
Ref work, you are lucky in that you can work anywhere which is good for your sanity as very few jobs here for women unless you are a teacher, teaching assistant or nurse.
I'm a family lawyer and sadly not much call for divorce lawyers in saudi, they either get another wife (can have up to 7 although DH can't understand why any man would want more than 1) or else they say 'I divorce thee' three times. I'm therefore a bit redundant!
Sounds like it could be a good move for you all to be there together for a while, particularly with the current situation in the UK. I have a few old lawyer friends who have their jobs at risk, hours cut etc.
I would say if you kids are young enough, go for it. You can save enough money to pay for their private school fees when you get back and pay chunks off your mortgage.
Hopefully, whoever he works for would provide a good package, ie free accomodation, house boy (male maid to do all washing, cleaning, ironing etc) travel allowance and school fees (schools here are all fee paying).
can you say who he works for? This may provide a clue to what compound you may be on and could give more advice.
