W is angrier after my 180's - time + consistency

[2thepoint]

I got approved on the apartment lease today. The apartment is not available until the 24th which is going to PO my W but it is what it is. Her parents arrive around the 16th and I'm sure W wants me out before they arrive so she can prepare the guest room for them and she can move back into the master bedroom where I'm currently camped out. So now I've got to figure out a temporary living arrangement until the apartment becomes available.

Earlier this morning my W sent me a text about getting an apartment (previously detailed) and my response back was "I've got it covered and please stop the pressure." I said this because yesterday she is sending me emails of apartments she wants me to live in and then the text earlier today about my progress cause if there is none, she's going to take care of it!

Six hours later she replies to my text as follows:

"I'm not pressuring you, just preparing myself for telling the boys. If we can I'd like to tell them a few days before you move. Where will you be living?"

So here's where I could use some advice:

First, I don't think she should be telling the boys anything in isolation. I need to be there when she drops the bomb on their heads and help to pick up the pieces of their shattered hearts.

Second, how best to tell the kids what is happening and how they will be impacted? I mean, part of me wants to give them hope for the future (possible R) but I know W is more likely going to want to be more final. The other part of me recognizes that it will be my W who decides if there is going to be a R and that is no where in our future from what I can see at present. I don't want to create false hope for the boys, even though I am hopeful.

So for those of you who had to break the news to your kids, especially ones that are the age of mine, what suggestions do you have?

Appreciate the feedback!!
