happydaisy - you have to learn to let go of some things yourself and give DH full and total responsibility for them. He may feel you are always organising everything and checking everything so he just gives up and lets you do it. Look at what you said.
"I've had to draw up a timetable which he can never be bothered to refer to.."
Can you imagine how that feels every day to have your day effectively organised by someone else handing you a schedule as they leave the house? That is very demotivating.
My DW has a tendency to try and micromanage everything by making lists and expecting everything to be done exactly her way at exactly the time she would do it herself and then checking everything twice when I have do it. She also unpacks the children's bags the moment they come in the house and she then writes everything down relating to school activities on a complex calender check sheet which she controls. She is worse when she is stressed or worried.
Rather as Triggles/Snorbs describe. I have to admit, I gave up fighting her over it and now just let her make her lists. I know what needs doing anyway but she needs to feel she has everything taped down. I have gradually gained control of certain things and have agreed she can have control over other things. That way we do not try and do each others job, we each contribute and we each take responsibility.
At the moment we are planning a house move and she is in full list making mode but in practice she has not done a single thing towards the move. She is happy feeling in control and I do not fight that but actually I have made all the phone calls, know what I am going to do when and have arranged all the utility transfers, booked the removers, and transport arrangements, chosen and bought new carpets and new kitchen equipment washer and dryer, etc. She actually did none of it but we did consult and then I got on with it and did it.
I do love my DW very much and over the years I have learned how to avoid arguements over things that do not matter while making sure the house work and kids get looked after properly. God help us if DW gets one of those O2 Joggler devices though.
