WIBU to call myself Cassandra?

[Cassandraprobs]

(disclaimer, mostly lighthearted!) Cassandra as in Greek mythology who made true prophecies but they would never be believed.

DH and dc have an irritating habit of expecting me to know what to do/be in charge but repeatedly don't take what I say seriously. Not too serious a problem to be fair but I feel like calling myself Cassandra round the house to run the point home

Example;

(Eating out) DH - "I really fancy the spag bol"
Me: "Oh, ok - that always gives you really bad indigestion remember?"
DH: "Does it? Oh, I think last time I just ate too much"
Me: "No, you say any time you have it you get a really bad belly"
DH: "Oh, well I'll just eat a bit"
Me: "Ok"

DH later - "I've got horrendous indigestion, I feel awful"
Me: (looking after him half the night because he gets quite ill with it) "Maybe you should steer clear of spag bol"
DH: "yeah, I'll have to remember not to eat it again"
bash head on wall

This happens almost daily over small things, I've tried just not pointing it out and hoping natural consequences kick in but DH just doesn't seem to pick up on cause and effect and dc seems to have followed suit. Or the consequences aren't on him/them! When the consequences are pointed out it's just "oh well, sorry, I didn't know" - maybe listen then!!

Anyone else get the same at home?

Natural consequences.

Don't look after him.
If he leaves you waiting around constantly because he's lost his keys, leave without
him or make yourself a tea and go wait in the car.
Mouldy towels. Throw them out, buy yourself new ones and keep them in your own cupboard. Let him wash, dry and use his own mouldy towels.

And I agree with @Sn0tnose
If this was my husband I'd tell him how fucking ridiculous it was and to stop it.

I agree with Sn0tnose and mrfrostywasadick - stop pandering to him and picking up the pieces of his stupid, selfish behaviour.

Presumably he is a fully functioning adult and is aware of actions and consequences, tell him to act like one.

The only people you should be looking after with an upset stomach are children or those who cannot take care of themselves.

I've got visions of you hovering outside the toilet door ready to rush in and clean up after him while he makes a point of going back to bed to rest!

Woman up and leave him to wallow in his own self induced problem.

If I knew he was going to make himself ill because he’s done it before I would totally go and stay at a friends! When dishes are still dirty I pile them back in the sink for him to wash again. It’s been ages since I had to do this, took a while but worth it. I put a pan back in the sink every day 4 days in a row years ago.
If you are feeling charitable you can say I’m not your mum, your PA, or your brain and I’m really starting to resent this. In sickness and in health does not apply to idiots who make themselves sick by deliberately eating something that disagrees with them even when ive reminded them, so from now on I’m going to treat you like the competent adult I know you can be.

He's doing this because you facilitate it. Do you need to be needed? Some people do. I'd find this very tedious and unattractive and would have lost patience a long time ago.
Honestly, do you not think it's ridiculous that a grown man doesn't know which foods make him ill and then expects his wife to look after him when gets gutsache? It really is exactly the same as a child who eats all their Easter eggs in one day despite warnings, and gets sick.
