Could I please ask of your relationship with your daughters now? How often do you see them and how do you get on?
I get on great with my daughters and am delighted by what well rounded responsible adults they grew up to be.
I think (again in hindsight which is a wonderful thing) that I worked too hard when they were growing up and as a consequence didn't spend as much time with them as I now wish I had. What I did always do though was try to maximise the quality of the time we spent together. I knew people who would say they couldn't have done the amount of travelling I used to do "because of the kids" but as far as I could gather never actually did anything with them when they were at home.
I relocated back to the UK near the end of last year so I now see both daughters regularly, say at least 2 or 3 times a month, although that will change next year if my eldest daughter gets accepted in graduate school in the United States. That will be strange although I suppose it means I'll just be collecting even more frequent flier miles.
They also have a good relationship with my wife. In the summer they went to meet their "step grandparents" in Finland. (Is there such a thing as step-grandparents? Obviously since my eldest daughters are adults that isn't how they think of them. Perhaps "my wife's parents would have been a better description?)
