I think LAT (Living Apart Together) is the way to go in these situations. You're in a committed relationship, but haven't blended your lives. There seems to be a lot of pressure on people to live together after a certain point. I'm not sure I'd be in a rush to do that again.The older you get the more complex your life gets. People have children, own their properties, have pets. Can definitely see the difficulties with trying to "merge" 2 lives in certain situations.
