I think he should contribute in some form - even if it is a few small things each day...
My other half needs to be asked to do anything
Even putting his dirty clothes in the basket - small things which usually require no thought when you are doing them ("oh I'm taking my dirty clothes off now, they should go in the dirty clothes basket, oh hang on I'm too lazy to lift the lid")
We just had a house inspection this morning - all the other half contributed to cleaning up was folding his clothes, putting them away and cleaning a few things up around his computer desk
Just sh!ts me that he doesnt think to contribute to the running of the household - its not like I am asking him to do everything when he gets home from work. I dont mind cleaning up cos I am a bit anal too when it comes to doing things - I like them done a certain way lol
But to reiterate (before I write a 10000 word essay) - it shouldnt hurt for a guy to make some contribution to household chores!!
