OP i had to check the date to see if this was something I'd posted under a different name.
Search Cassandra Syndrome. Also Ongoing Traumatic Relationship Syndrome. Also Maxine Easton. These are not diagnoses, rather they're unofficial descriptors of what happens to you when you're in the sort of relationship you're in. Some people say that as they're not official diagnoses that means they don't exist. I'd say that some people think things don't exist if they've not personally experienced them...doesn't mean they're right.
The issue of being abroad is an absolute fucking nightmare. I had no idea what it meant when things like this happen. Getting divorced when you've been in other countries for your spouse's work (and often can't get a work visa in those places, don't have the right qualification or can't get work because you don't know exactly how long you're going to be there anyway) takes divorce nightmares to a whole other level of hell.
Then there's this situation of being profoundly alone. Alienated in some ways from everything around you: people, culture, language - even weather sometimes.
And a partner who doesn't recognise you're suffering, or your emotions really.
Honestly OP, it's beyond the capability of anybody to withstand that all for any length of time. There's absolutely nothing wrong with you. The problem is your environment. All of it.
My children are now older than yours. When they were the age of yours, I was also in a situation which made divorce impossible - well, technically possible, but I'd have been in an insanely shitty situation abroad and unable to leave country..and unable to work there because I didn't speak the language well enough to function! I started studying with the OU to give me options. It also gave me hope, which is very useful to have... If I were to go back in time, I'd have done it full time, not part time, so I finished faster.
Something to keep in mind is that soon travel back to the U.K. will be possible (without the hotel quarantine). And usually (double check this with an international divorce lawyer) if you file for divorce in England (specifically) then regardless of where you live, the divorce can proceed there. If, however, he were to file for divorce first in another country, that's where it would happen. Just something to keep in mind.
There is no magic bullet here, but there is a way out. You need a plan.
- You need to decide somewhere you want to end up and how you're going to get there. - Speak to international divorce lawyer based in that country (some have a free 1/2 hr).
- If it's back to the U.K., then definitely make contact with old friends. You have nothing to lose there. Keep it light though. Ask how they are doing, say you've been thinking about them. Some may not reply, others may. If nobody does that won't be nice, but you won't be on a worse situation that you are now.
- Tell any close friends or family (hard when you're away, I know), what's happening, so they can support you. Again, if they don't, you're not materially worse off than now.
- look for a therapist who is working online. There are a lot due to Covid. Ideally you want one who knows what it is to live as an expat spouse.
- Remember that your children need you far more than they need money. It's scary to imagine a big drop in material things, but what will disadvantage your kids more than anything is an unhappy mother. Especially when their father isn't involved in their lives that much.
You might need to engage some childcare too (even if "only" to give yourself a chance to breathe). If DH has an issue with this because you're not working, then do it anyway: it's not like he's being much help and looking after children is work. It's just unpaid and thankless.
Finally, you're not alone. The situation is rare in it's complexity, but you're not the only one. And there really is a way out of this and you definitely can do it. But the key is that you need to. This is a situation that can't improve for you if you do nothing. It's not easy though, to make the changes, but it is something that can be done. There is hope here, even though I know the weight of it all and the bone-permeating loneliness is utterly overwhelming.
