There is so much good advice here and I think you know that the sensible answer is NOT to go.
Perhaps for the hotel period for a week or so, but 4 people in a hotel room? Ok out there it could be a suite so you might have room for you and another for kids, but if it’s booked by corporate… I doubt it.
I’d check on that first and foremost
I would recommend you don’t go at all. I think that there is MORE chance you’re going to split up if you DO go than if you don’t.
I also wonder if your PND was caused by his attitude to parenting.
I wonder if, with him out of the picture, you will fall into a routine that works for you and the dc and you will thrive (as will they)
The added details of your little one and potential high needs etc? The ethnic issue in a ME country… it’s all icing on the Hell No Cake.
My advice to you would be to say that you will/will not come out for hotel stay - totally up to you, it will be exhausting. But it’s neither here nor there in the greater scheme of things.
As regards to moving, I’d say to him that he needs to go ahead of you, that he needs to pass probation and know he wants to stay, then he can suss out the lay of the land regarding accommodation and nursery and then (and only then) will you be in a realistic place to make a rational decision
My guess is that by staying home, you’ll gain in strength and if you carry on with the counselling you just might be able to fix things a bit better and who knows your marriage may survive
I think given the huge pressure on trailing spouses at the best of times, all the little details you’ve shared with us on top of the marriage issues, you should tell h that this way of doing things would give you all the best chances of survival as a family. He needs to focus on getting himself settled and YOU need to focus on getting yourself to a happier place and at this point neither of you would have the bandwidth to achieve this and help each other
Not going is not you calling it a day, it’s not you leaving him, it’s both of you allowing each other the space to focus on very important changes and to keep talking on WhatsApp etc will keep you connected
I think this space could actually help save the family
