It's amazing the amount of vitriol and "don't do it" - all from people who never have done it!!!
I've just repatriated after 8 years as an expat, much of that in Dubai. I loved Dubai, but it is not right for everyone. If you do go, your success will depend on the attitude you go with and the plans you have made.
- make sure that DH's package will cover all the essentials. Look on www.expatwoman.com - a goldmine of information
- Be realistic about the career prospects for both of you and the risks and benefits. Boots has stores in Dubai - why not contact the relevant department in Nottingham and see if there might be opportunities.(I worked for Boots for 12 years and even managed to do some work for them in Russia)
3)Think what your exit strategy would be if DH lost his job. Can you manage to have a rainy day fund set aside. Can the package include repatriation costs.
It would probably be better if you could wait in the Uk till DC is born, but after that, if you are in Dubai, you can get masses of house help easily. There are good medical facilities (make sure you have health insurance as part of DH's package) and good schools when you need them - just get the DC's names down now even if you think you might leave before then!
You will miss your family and friends, but there's SKYPE and you'd be amazed how suddenly you have more friends than you ever dreamed off once you are living in the sun.
You'll have no problem making friends. Everyone has been through similar experiences and there are masses of clubs and activities for SAHM's. Women support one another strongly as nobody has family there. I made loads of long term friends, now scattered all over the world.
Someone above mentioned about a 1hr school run I think - not normal. We walked to school, except in the summer. Lots of people do now stay in the summer hols. Everywhere is air conditioned and every year there are more things to do.
You can have a great, easy and financially rewarding life in Dubai, provided you obey the law, don't get into debt and generally just be sensible. If you are ever going to move abroad, do it now whilst the kids are young. I've moved back and DH is still abroad because I needed to get DS settled in a UK school for GCSE and A levels.
Try and go see. The surest way to make the adventure fail is if DH drags you kicking and screaming.
Good Luck, whatever you decide. Any specific questions, do ask. There are several Dubai experts on here.
