Just read this Guardian article with interest link
TLDR: it's not about how much a man helps in the house, it's about how women are almost always in charge of the household - expected to know what needs doing/paying/renewing/cancelling and when and either to do it or direct their partner to do it. The author calls it a 'mental load' which men don't have to put up with - they wipe a toilet and feel satisfied they are contributing.
It really struck a chord with me, especially the bit where the tidying of a simple table generates a whole list of additional tasks, but all the man sees is that a table has been tidied. I am totally in this position - always feel like I am forgetting something and it's on me if anything isn't done, always mystified when DH claims completely sincerely that he does even near to how much I do. I always thought I had taken on the role myself - but this made me doubt that.
Thoughts?
