OP, I appreciate that perhaps you are having problems that need help, but, really, you are taking the piss.
Eight hours is VERY little in terms of actual paid work, your children are of school age, you have only two of them.
Put simply, your leisure time is much, much more than your dh's.
FFS, get a grip on this. Your husband has every right to do f* all at the weekends. This is not a gender issue, if I worked a full-time job and my partner only 8 hours and had school age kids, I'd be mad as hell if I had to wash a dish unless in unusual circumstances (partner ill, away etc).
You may have problems, but seriously, projecting this onto a totally unfair attack on your dh will not help. If I were him, I'd think that you were being totally unreasonable and I would be so pissed off, I'd consider ending things.
If your dh did this, and you became a single mum, I can assure you that you would find out what genuine hardship is in terms of time -if not financial- poverty.
