DH and I have been talking about living abroad for years. When we had DS 3, we stopped talking about it and settled down to the daily grind of working, commuting and childcare. Both of us are fed up of it (although who isn't TBF!) and DS has started to get exhausted from being at nursery full time so weekdays have become one big long battle from the time we get up to the time we put DS to bed. We both find it very hard to tolerate the long dark UK winters and apart from our family who we rarely see due to work & childcare commitments we could keep in contact over Skype or email in the same way we do now.
We would both be classed as skilled workers under the visa application process so as long as we can both secure jobs similar to the ones we have now, the sums seem add up and it looks like we should be better off than we are now. The school's look comparable to the UK so DS education would be taken care of.
We love the more relaxed culture, the sun and the nature. The main problem is that our family would be very upset and quite possibly wouldn't talk to us for a long time and would probably never visit.
