Why not retain after you're served?

Don't have any expectations until she gives you reasons for them. they will only end up hurting you if things go south.

You have to be able to SEE action, not just hear it. Access to her phone is great, that's action. calling a MC for both of you is action.

If you're serious about not going back to the old M, make sure you're maintaining your boundaries;

This is when she'll start to test them to see how serious you are.

Remember, too, that she's sitting on the fencepost. She has 60 day until the paperwork expires. My guess is she's counting down those days just like you are...That's not "I'm willing to work on this" that, to me says "I'm willing to give this some time to see."
