My wife and I come from very small families who are not particularly close. We have found it pretty easy to settle. In my case I had lived my whole life (54 years) in SE England. Was happy enough there most of the time but so far have not missed anything or anyone. Skyped a fair bit at first - in fact I communicated more with family in the 6 months either side of moving than I had in years but it has returned to normal now. Rare!
