NO WAY.
Women are without rights in that country.
I wouldn't even go with a supportive husband.
I 100% wouldn't go with the kind of husband who comes home and ANNOUNCES that he is going, has a good 'package'.
That sounds like the kind of husband who would be all too happy with the thought that once you're there, you're unable to do a damn thing, including leave and come home, without his permission.
DO NOT GO.
You will live to regret it - you will be entirely under his control while he has the freedom to do anything he likes with no comeback. And you won't be able to leave.
The kind of husband who announces this is to be honest the kind of husband you end up splitting from anyway. Go to your family. Let him stay there. Be super gracious and make damn sure that money is coming into accounts you have your name on.
See what happens, but prepare for a split. Don't think of it as wasted years - you have your DC, you are young. Get planning once he's out of your hair and you have some breathing space with your family.
You'll be ok.
But don't even set foot in Saudi Arabia.
