Wife dropped the bomb; doing in house separation

[HopeTex]

Curious if anyone has any thoughts on in-house separations, specifically sleeping arrangements. We have a 3 bedroom house: Master, room for the twin girls, room for the boy. So no real guestroom.

When she first dropped the bomb and asked that I move out to an apartement we both stayed together in master bedroom for two nights. Then when I said I wasn't moving out of the house but that she should if she wanted out, she moved to the sofa for a few nights, then started sleeping with the kids.

(She said a few weeks back that we needed to have a conversation with the kids "Daddy and Mommy are having a hard time loving each other right now, that is why we aren't sleeping in the same bed, etc, etc.". She was pretty adamant about having that conversation with the, but never has. Of course they are young but not that young, am sure they know something is up. So far W just says "we are doing a lot of slumber parties this weekend.")

Then our MC suggested to me that it would be kind if I offered to trade weeks in the master bedroom with W, so I did. When I am out of the master I take over the girls room to myself, because I want privacy and because I don't think adults need to sleep in the same room as kids that much. I just put the girls in with the boy - he has a huge multilevel bunk bed with a trundle that can sleep 4 kids easy. When W is out of master she usually leaves the girls in their room and she goes and sleeps in boy's bunk bed with him.

I get sick of the weeks when I am out of our master, but suppose i can live with it. But does anyone see anything I can do better here? Anyone think it would be better for me to move back full-time into the master and tell W she us free to join me or not?
