What to do when an EA involved?

[Hoju]

She told me last night she put in an application for an apartment and can move out as soon as september 1st. We are also going to sit down tonight to divide up the house and assets for the separation. I'm so lost I really thought she was noticing the changes i've been making. This is all becoming a reality and at such a rapid speed, she still seems really upset and guilty about the whole thing, i'm trying to continue to validate her feelings without supporting them, which is almost impossible.
