Her subtle changes, do they mean anything?

[blue2010]

I am trying to figure out what is working vs if she is just pretending. She says she still plans to seperate I told her to spend this week away she did with minimal contact. But I cannot tell if she is putting up a front or is acting nice out of sincerity. She quick to end the good night call to kids and the other stickler of the week is a confirmed call from OM for closure. She was angry again after that calm again today. I feel like I am on a loop de loop.
