Treading water - time and patience

[NYCPeter]

Ok - well this is a shocker (maybe not to some on here).

I called to speak to my girls, phone was picked up by D6 and we chatted for a while about here day (I'm so looking forward to seeing them tomorrow).
D6 says "Mommy wants to speak to you" - great....

W - Did you get my text
M - Yes, I plan on coming back on Friday
W - Peter I'm serious
M - So am I
W - This is the only avenue left to try to fix our M (meaning trial seperation)
M - I don't think that's the case - lets talk tomorrow
W - You don't get it - if we don't seperate I plan on filing
M - (After catching my breath) - I really think we should discuss this in person
W - Ok, but I'm not changing my mind.
M - Speak tomorrow.

Now what?? I stay in the house, she says she'll file. Moving out is not something I want to do, but she may file anyway.

How do I turn this around? How do I make staying in the house not about me? It's obviously beneficial to the girls.

Help....
