Sorry this is long and moany 
He's going away to work tomorrow for 3 days. Over the weekend I said he'd better let the bank know so there's no problems with his debit card (online banking so he just has to log on and click). He didn't. He'll be driving for 10 hours in Europe; tonight he said he would take food with him so he didn't have to stop. I don't have anything other than Dairylea triangles and Froobs, so I suggested he pop to the local supermarket (literally 2 minutes walk) as they've got a brilliant little 'lunch' fridge with sandwiches, wraps, fruit etc.
He just said he can't be bothered, he'll 'find something'.
He's sitting watching telly now, I asked if he was packed - I did all the laundry today and put all his clean stuff out on the bed so he could pick what he wanted. He said he'll do it in the morning.
He's leaving the house at 6.30am.
I asked if he had all his paperwork etc - he said he 'knows where it is'.
Bloody hell!!! 
I know he's going to wake me up at oh-fuck-early panicking because he can't find something.
This isn't unusual; if something needs doing he tends to leave it and leave it and I usually end up doing it. Except for things that I CAN'T do, like make him go to the doctor to get the blood test he needs before they'll give him any more of his tablets, the ones that he ran out of in APRIL.
I just told him that I'm not his mum and it's up to him to get his stuff sorted, and not to wake me up in the morning panicking because he can't find something.
And now he's all huffy. And I'm going to be ever-so-nice and go and apologise, cos I can't let him go away while there's bad feelings.
But AIBU to make a stand and STOP picking up the slack when he doesn't do stuff? It will make life really awkward for a while, I just know it will.
