Yep @joannie living on your own helps. There is less mess, usually, and you aren't a slave to anyone elses need for order or routine.
BC version 1, my son was 13. I'd been a sole parent for years. I was often told I was too hard on him when he was a small child, usually by the competitive martyrs who would go to extraordinary lengths to prove that they were the '''best' parents. As it turned out, he was more than capable of cooking himself a meal and could be trusted to navigate the 700km journey between home and my mother's via train and bus when I knew I wouldn't be able to look after him while I was having surgery in Melbourne.
I was well enough most of the time to work, but during a couple of crappy weeks a very kind lady I didn't know well offered to launder his school uniforms. Housework, meh, it's a small house. Boys of those age smell so appalling (despite an hour a day in the shower) that there is little point in worrying about any more than the basics, if he wanted to live in squallour in his room/cave, so be it.
Water finds its own level. What happens if you stop driving the requirement for a 'proper' domestic environment? There is only one way to find out. It's an interesting experiment and what harm can come from three months of accumulated dust?
