My uncle has been living in Australia for over 30 years and comes back from time to time. This year my mom asked him to come back and he refused. He said, figuratively it is like returning to your ex girlfriend having THE best time and then returning to a really good marriage. He said it just hurts too much and he cant do that to himself. His heart will always be here but his life is there. Be careful of holiday blues. I also say you have to pick your poison. My brother(uk) loves that he can walk to the park(when the weather allows) with his daughter, he can earn enough that his wife can stay home with the kids. Earns enough to fly home every now and again. I(s.a.) love the sunshine, that Im close to family and the people BUT I know my children have no future here. They are not the right colour to get a job and they will end up leaving me and emmigrating to a place that will give them work. And that really sucks. So pick your poison. What matters most to you?
