Chandon as someone who is often out of the house for 12 hours working, I acknowledge that people need a 10 minute break on coming home from work, but this is trivialising the issue. If it were just about this problem, it would be an easy negotiation.
OP Wifework is a great read, albeit it is a rather old text now. However, what's sad and depressing is that this forum alone proves that much of its message is still so relevant.
Don't beat yourself up too much for letting it get this way; you are 50% responsible for that and no more. What you must never forget is that this isn't just about the expectations your H has of you, but the expectations of others in society, you have absorbed and are still absorbing.
To illustrate this, have a think about who would be blamed more by others if they visited your home and it was a tip - you or your H? Who would be blamed more if your DCs turned up at school with dirty or unironed clothes? If your child went to a party without a present?
This is just as much a problem in society as it is in relationships. Society blames women when these things don't get done, far more than it blames men. Other women (like Mums and MILS) are often the worst offenders for these double-standards, too.
I would also say, don't aim too low in your expectations. It sounds as though you write off the weekday evenings as far as his contribution, but are they written off for you too? When he comes home at night, does that mark the start of your leisure time too?
I cannot stress enough that dividing work is not about tasks, but about responsibilities. This really does work best when you work on a cradle to grave premise, so the responsibility is for laundry right through the process from washing basket to its reappearance in a cupboard. Other tasks can be divided up more discretely, so whoever cooks, the other loads and unloads the dishwasher or washes, dries and puts away.
Your H also needs to appreciate that families need to play together and that your DCs are not going to be satisfied with days at home every weekend. We all need a complete down day at fairly regular intervals, but with DCs, it's all about compromise, especially when they are young and need entertaining.
There is something else I want you to focus on. I write most frequently on infidelity threads and I am often trying to explain that infidelity happens not when an unfaithful partner is not "getting enough" from the primary relationship, but rather when they are not "giving enough". The situation you describe in your OP and subsequent posts could have been tailor-made as a case-study to explain this concept, especially when I see the manipulations your H is enacting about sex.
I must reassure you that I am not suggesting that your relationship is about to be blighted by infidelity, but I often wish I had the opportunity to intervene on here before it comes to that. It would be a shame if posters who had suffered infidelity in a partner ignored your thread thinking this had nothing to do with their situation, because I have seen so many threads now where in the aftermath, posters start from the premise that their faithless partner wasn't "getting enough" from the relationship, when it actually emerges that s/he wasn't "giving enough".
