My DH is a shift worker, and a couple of years ago he would work a week of late starts do we were like ships in the night. It was hard then as we were planning on buying our house. So I *had* to make a lot of the decisions. But it grew our trust in each other.
I don't like to be apart from him for long periods but I do enjoy my time alone too, and do does he. It makes us enjoy each other better, and we have stuff to talk about.
My grandparents have been married 65 years, my grandma says its only because he was at work that they lasted that long! He would have driven her crazy otherwise. And she raised 8 kids!!
DH and I are both independent people who are dependent on our relationship. ITMS!
