Hi Lavender,
I've followed your thread since pre-flight. I've read your words as you've ummed and arr-ed about leaving, your worries about the children, your hurt, your frustration.
I've read as you've established yourself back here and just tried to get on with things.
Despite my sympathy, and empathy for you (of which I have a lot), I'm going to be brutal:
STOP! JUST STOP!
If you are not feeling well now, how are you going to feel the closer it comes to him arriving? How are you supposed to manage the next few weeks if you are already feeling sub-par? What happens if sub-par becomes thoroughly ill?
I know first hand that the fear of the future is often much worse than the actual present proves it to be. Your mind works overdrive, your sleeplessness and your anxiety feeds the fear. When it actually happens, it's manageable. But you don't realise that until you are in the moment.
I know that your new life is now being bastardised by his re-emergence. I realise that is very difficult to accept, and to deal with.
But your solicitors have made this point: suck it up in the short term to gain in the long term.
You don't have to, but either way there are consequences. You are in between a rock and a hard place. Of that there is no dispute.
I really do feel for you. I really do have a lot of compassion for the difficulties you are facing. I am an expat, and an expat wife too.
Please, love, just make sure you are in the best position to cope with it by taking care of you beforehand - not dealing with it during or after.
It is more than likely the afflictions you are currently suffering are stress induced. You are building up to a period of more stress. Speak to someone (a GP) to help you cope with it. It's not admitting to weakness, it is recognising the uniqueness of your situation, and getting support to manage it.
You've got this far and you're fighting to get further. A little GTX in your fuel right now will help your engine will not hinder it.
Best wishes.
