Sharing a home when seperated 

Nuts and berries?  Hmmm have to think about that one. But I totally see your point.  We have been together 13 years and this is the second time in marriage counseling.  He is in the guest room (which has the only TV!).  The kids have starting calling it "daddy's room" and seem fine or at least haven't thought of asking any questions about why the switch.  
Counseling doesn't seem to positive at the moment and my energy level for fixing things is low, I have done it too many times.  But leaving the house for either of us seems to be too hard because of the kids and we love where we live.  We have talked about having the house be the central place for the kids and we do the shuffling to keep them sane.  We also have a large basement, mostly unused with another bedroom and bath, not as nice as upstairs but still very livable.  I guess it seems a dream to get two people to be sane and work through it very rationally but he is very jealous and possessive and would want to know my every move.
Getting an apartment nearby is a possibility for either of us but with finances a concern and the economy going for a dive I am concerned about the cost.  
I was hoping for a fairy tale story of a couple that woke up one day and realized they were not made for one another and decided to be great friends and disgustingly civil to one another while they worked out the intimate details of their complete and utter separation, keeping in mind they will always need to communicate because of the kids.
If I sound totally confused and baffled it is because this is my constant state of mind at the moment.  
Maleficent:  Thanks for your comments and positive energy.  My situation being somewhat the same as I am the one who has to find a job after being a stay at home mother and slave to his every need...Did I just say that?  Super duper sorry!

I co habitated with my ex for 1 month.  Best bet is to leave early in the morning, get home just in time for bed.  After a week I was ready to pitch a tent in the woods and eat nuts & berrys.

The flip side of the coin was that her actions solidified my resolve that I was making the correct choice in divorcing her.

Jess, I know exactly what you're going through. My husband and I are having to co-habitate until this semester of school is over for me and I can move out in December. It's certainly not easy and I find it's easier to think about everything clearly when he's not around. We're civil with each other and don't feel the need to avoid one another, but the tension that we are eventually going to live apart is always there in some form.

Keep busy. Do things you enjoy apart from him as much as possible. Get caught up in work or immerse yourself in something positive. Try to maintain civility and do whatever you need to do to stay as comfy within the situation as you can be. Remember, it's only temporary!
