Once again, thanks for your replies and for the kind wishes.
I can make a call on his phone, but it's HIS bloody phone, not mine and I have to ask as it's required for work calls. I have my own phone but I can't make international calls on it and I can zoom my UK friends but you know when you just want a good old winge about your DH with your tribe, you don't want to do it with him in the next room. He's been working from home due to CV since February. This is probably part of the problem.
I could take the sale in hand, I may have to, but I had been navigating this for 18 months and dealt with many issues and had had enough. I was exhausted, I became ill, I'm now recovering. He said he'd deal with it.
I could return to the UK for a visit but I need the permission of his company and the local govt to return. I also need to isolate in a hotel for 2 weeks, longer if someone on my flight tests positive, at my expense and many people are not being allowed back in, it's a bit of pot luck. Many countries in the world have closed their borders and we are in one of them. Very CV safe but not great when you are homesick. I should have been home for 2 months earlier in the year, maybe another part of the problem?
I was volunteering, CV put a stop to that, I had planned to take an academic course, same thing happened. I can meet with friends in groups of 5, that's enough and is a great help. I'm putting myself out there in the expat world, it's just a very different life to home and I'm taking time to adjust, I guess.
We came here because we had no choice, his job required it, it wasn't part of the bigger plan and we're not chasing big money, expat packages are not what they used to be. His company would not accept me staying in the UK, we tried that, seriously, they wouldn't!
Thanks again, your input has been really helpful. It's 'wine o'clock' so I'm off for something cold and wet.
P.S he phoned the solicitor!
