Answer to: "why didn't you hear it from ME?"

[Flight]

What if she wants to have a talk about changing the in-house separation to a physical separation? How do I handle that? We met with a third party to just talk about where we were and they said "why don't you think about it for a few weeks and let's get back together and see how things stand?" I think that was just giving me lip service to say "see, I tried". I think she is going to want to say it has been a few weeks, things haven't changed, who is moving out? I don't feel I should have to draft a separation agreement or do any work on it. It isn't my idea. How do I validate that??? Or do I try to keep stalling?
