She's most likely trying to escape as much as she can while she is away. Don't be surprised if it hits her like a ton of bricks when she gets back, and resorts to old methods of intimidation to get you to comply and let her have her way.
Remember for now an amicable separation is your goal. Depending on how much she changes in the next few months then maybe you can start looking at a reconciliation.
I also recommend you make a list of what you want in your marriage. She may come back trying to negotiate some sort of crazy deal where she gives you very little in exchange for a lot of sacrifices on your part.
Your mindset from now on should be: "I want the following, and will not settle, even for you W"
