I don't know. I can understand it, and can imagine me feeling that way if, for example, the unthinkable happens and I was to split with DH.
We waited a long time before moving in together - both had our own places and space. But it isn't just domestic drudgery - it's a shared lifetime. It's making a home that is 'ours' and the little routines and rituals that mean nothing to anybody else but help get you through the day. It's waking up in the morning next to someone you love and listening to them breathe. It's not coming home to an empty house and knowing that when you get in, there's someone who will be glad you're back usually.
Having said that, I didn't wait until I moved in to start farting in front of DH
and we used to bicker about who did the washing up at whoevers house we were at...so he was probably in a lose-lose situation anyway 
We also respect each other's need for down time and keep finances pretty separate - we earn equal amounts, put the same into the bills/savings and the rest is ours to do as we please, which I know is a bit of a no-no in MN terms.
We also have no DCs. I think not having DC's and having separate finances is the key to a successful relationship personally 
I don't think you're odd for wanting it - but I don't think it neccessarily makes for a happier relationship. And I certainly don't think it makes you any less committed to a relationship if you chose not to live together.
