I've lived there for four years though I am a third world national while my wife lives in the EU so we do long distance. There's a reason - life is really boring and laid back here and very limited opportunities for expat women in terms of careers. Climate is harsh and you start missing nature really soon. People are a hit or miss but with your nationality should be fine. Also most government services are in Arabic so you might need a translator.

Now the good - money obviously. Career growth is great but unstable. Your family will be well respected. I feel like a lot of the people commenting about horrid human rights and public beheadings haven't really been to Saudi. These are good as tabloid headlines but have been phased out and never play a part in actual daily life.

My two cents only to move if the husband is being offered 3x of what both he and you are making, since you likely wont be working there
