"Although when I asked him why he just assumes I will do washing etc he couldn't actually answer my question and just sat that looking a bit wet really."
That's the spirit
I think Pheebe is right though in that "I have just said to him that if he doesn't help out more then I am going to stop doing his washing etc" is very vague.
For a start I wouldn't talk about "helping out". Your children "help" around the house. The adults do their bit. What you want is not for him to help a bit but for him to take responsibility for his share of household tasks. He is an adult and needs to act like one.
What is it that you want him to do?
In the most recent example he didn't take the load off you when you were ill, so that could be one of the things you say to him:
"When I'm sick in bed I need you to do run the house until I am better. I will do the same for you. That means that the house should be reasonably tidy and the washing up done."
Then think about what else seems fair. He works full time, you work about 4/5ths of full time. So what seems fair to you?
I would guess that as you are home earlier than he it might make sense for you to make supper on weekday evenings. If you do that, he could do the washing up on those nights, perhaps?
Do you like the house to be quite tidy when he isn't so bothered? Well then you could take responsibility for that but ask him to be in charge of laundry.
Whatever you want, you need to be clearer about it than saying he needs to "help out" or else.
Try to get him to agree a way to share the work. If he won't agree to something you think is reasonable it is probably time to think about counselling to figure this out to both of your satisfaction. Don't underestimate how much of a problem this kind of a problem can become.
As long as you are not happy with his contribution, don't do work for him that he could do for himself.
Pheebe LOL at my attitude leading to divorce
I come from a good Catholic family with no divorces I'll have you know
None of the men in my family that I respect and love treat their wives as skivvies. Not my dad, my BIL, either of my grandfathers, or any of my uncles.
TBH I think it is pretty disrespectful to assume men are not capable of acting like adults and pulling their weight and just giving up on this generation and trying to make things better with our sons.
