Sorry to hear you're not feeling too great Trinity. I don't know if I can say anything to help, but I understand because I've got a lazy dh too.
What got me down (and I mean 'got' because he daren't do it anymore) was when he used to say "that its your job (childcare, housework, decorating etc)". Like your situation he'd say he goes out to work, that's his job, and all the child/house stuff was mine. For years he'd say this, and I never quite knew why it would rankle me so much. Then I fugured out the rather obvious reason, and in a fit of rage I told him and ever since he hasn't mentioned it again. This is roughly what I said:
"Yes, these things are my responsibility, BUT IT IS NOT MY JOB. If it was my job, I would be salaried, at a minimum of about £6 an hour. I would have a start time and an end time. Regular breaks, and an hour off for lunch. I would have a manager to tell me what to do and/or staff to delegate to. If I wasn't feeling particularly well one day, I'd probably take the weeek off sick. May even throw the odd sicky from time to time. And spend those days in bed, under my duvet. I'd have about 5 weeks paid holidays a year, where I don't have to think about work at all. If it was a 'job' I'd enjoy adult company and conversation. I wouldn't have to kiss my colleagues bumps when they hurt themselves or wipe their tears away when they are sad. Nor will I have to wipe their bottoms. I would physically not have to bend down to accomplish every task with them. I'd probably get some respect and kudos from my colleagues for doing a good job. I'd get apr's from my manager to guide me on my way. Maybe a payrise or promotion for a job well done. If I get all of this starting with the salary, then I know this is a 'job' I do, AND YOU WILL BE LEFT TO DO YOUR SODDIN JOB WITHOUT INTERUPTION FROM ME. Give me all of that and I will do my job. Until then shut up and accept I do my 'responsibilities' as best I can, and if I need help from you to do it I will bloody ask. And until you provide me with a salary and everything else you will bloody well SHUT UP AND HELP ME. Discussion over."
This was quite recently, so its still early days, but it is working a lot of the time. I have two more tactics if you're interested. The next one is to shame him. I've been ill lately and my neighbours know this. Dh would not cut the grass for the last 6 weeks, it was about a foot long. I got fed up waiting, so when he was out I (unwisely) did it. Four neighbours came out to ask why I'm doing it and not dh and I told them he's not bothered about it. On his return I told him. We had some heavy things that needed moving, so I got my 79yo dad and 7yo ds to help me. One more thing to move and my friend's dh has promised to help. Dh is suitably very embarrassed. Finally I caught myself saying something really bad just yesterday. He came to me and said "I'm sorry I've been so lazy" to which I answered "sorry I've been a bit frigid lately" (bit of a low sex drive lately which has been frustrating him). And then (I've no idea where it came from - honest) I added "maybe the two things are connected". They are not, but its given me an idea, if things don't continue to improve. Yes, I know I'm a cow.
Not sure what your answer is Trinity. Keep trying to communicate with him. Good luck. And happy birthday to your dd! Sorry about this being so long, but lazy dhs really get me.
