gingernut, a one off night off will not rechaarge your batteries, you need a bit of a life shake up so that your batteries don't need so much recharging.
I was nodding as I was reading your second to last post "just seems like his life has not changed too much to be honest and that he does just help me out every now and then"
That so rings true with me - we had these two bundles who took over our lives and to be fair to DH, he did EVERYTHING when they first came home from hospital (8 weeks in scbu). Then they became gradually more demanding and he became gradually more elusive. It all came to a head when i realised i worked as hard as he did, and I was still doing the early morning getting up at the weekends and he would surface about midday claiming we had made lots of noise so he couldn't sleep!
I have just realised we have turned this thread round from being "I am knackered, am I ill thread" to a "It's all your DH's fault" thread and that wasn't my intention - My point I think is that you need some time to yourself, REGULARLY and you should incorporate it into doing exercise too. My point is also, and I think you already agree with me, is you shouldn't be asking your DH to HELP, she is his child too, he isn't doing you a favour at all, it's just something he should be doing without batting an eyelid.
Without going into graphic detail, it came to a head with me and DH and after some drastic action on my part (talking wasn't working, he wasn't listening), we are now back on an even keel - he trains twice a week (no games now until september), I swim 2 or three times a week, he goes out with his mates once a week maybe and I do too.
This is gonna sound sickly, but I face each day with a smile now because theres things to be done, places to go, people to chat to and I have loads more energy. It's not longer the same old same old - it's very hard to muster energy in the mornings when you know it's going to be GET UP, FEED DC's, PLAY, NAP, FEED AGAIN, BATTLE OF WILLS OVER SOMETHING, FEED AGAIN, BATHTIME, BATTLE WILLS, BED, DINNER FOR DH, SLEEP.....
