DH is a consultant engineer and also a -workaholic- conscientious person. He has always had some international travel - usually over and back to the UK and within Europe, so 1 day or overnight, couple of days at most. But he has just finished a project that required him to spend 2 consecutive weeks a month in South Africa (and sometimes those trips were 3 or even 4 weeks) for 3.5 years. He has a lot of projects on the go at any one time, and is responsible for a large enough team (in engineering terms) here at home.
I am at the top of middle management in the civil service, but have also always been pretty -workaholic- conscientious. The past 6 years, since just around the time the economic crisis started, I was in a section deeply embedded in the crisis and recovery work. So lots of dealings with the political system and heavy heavy workloads, with lots of emails into the night (on blackberry, oh no, couldn't possibly be given a laptop to deal with stuff out of hours) and detailed economic stuff to do. I have moved 3 months ago to a new section where there is still a number of big projects to complete, but there is slightly less time pressure on them (still need to progress them quickly, but not "the Minister needs a speech we forgot to ask for in the next hour while you finish answering 3 different letters on different subjects, chase 4 other Departments and correlate data to produce 5 different trends to consider where we take actions, and tell me what those actions should be"). I don't have huge teams, but I don't have enough to do all we have to do. In that last job, I had the alcoholic (binger), 2 different major health problems for others, the one who wouldn't do what was needed, the one who couldn't do what was needed, the one who micromanaged and constantly changed goalposts, and the 2 who were great and got on with anything thrown at them.
We both work in the city centre, about 12 km away from our home. Commuting is awful - DH cycles while I drive/bus/train depending on what's on, weather, how I feel etc.
DD has Asperger's syndrome and ADHD. So that adds it's own complicating layer.
We live in a city 2.5 hours away from both sets of our parents, but they are near each other so we cover both when we go "down home" for weekends. There is some of my wider family near enough if we are really stuck for help, but we are pretty self sufficient. The neighbours are great though, our cul de sac has a great little community.
But DH is helpful around the house when he's here (and I used to be under orders even when he was travelling to leave the ironing until he was home). We used to have an au pair when he was travelling. We have had cleaners in the past at different stages. And we are both pretty ruthlessly organized in lots of ways. So it works for us.
