I moved to the North of England from Hampshire about 15 years ago, but always told DH that if my parents needed me I would go back. Now we have 2 DD 10 and 5 and have very portable jobs so could easily get agency work. I would like to move during the summer holidays in 2016 so that DD1 starts secondary school in yr 7 (she has ADHD so moving during a school year would be especially difficult for her). DH is willing to move, despite the distance we see more of my family than his. The issue is DH'S son who is 18 and has lived with us for the last 2.5 years. He has a fantastic job here and wouldn't come with us, and DH and I are struggling to make a decision that feels like we might be abandoning DSS. But he would be 20 by the time we move. Any thoughts?
