Treading water - time and patience

[NYCPeter]

So I plan on calling the house tomorrow to talk to my girls and then talk to my W. I plan on telling her the following :

1. Walking out yesterday was childish and I was wrong, to hear some things said on your anniversary is not a pleasant experience, but I should have risen above it and my primary responsibility is as a parent and I should be there for our girls regardless of the situation.

2. I will stop by the house on Tuesday night to see the girls and pick up some things.

3. I will be returning home on Friday - hopefully that will have given us both some breathing room to think things over a little.

4. I will not be moving out of the house - It's not in my or the girls best interests, we can't afford to maintain two places to live and I want to see as much of the girls as possible.

For the last two weeks we have been sleeping in the same bed (though nothing intimate) - what should I do when I return on Friday (my W will be working that night), just assume the previous sleeping arrangements are in place. If she says she would like me to move back to the spare room should I hold my ground?
