+ Part of me feels like WE need a break. She needs time to process emotions, reduce the negative stuff, rediscover what brought us together.
When you leave, she will indeed process emotions. She asked you to move out, she is preparing already emotionally. This is a new beginning for her and she is waiting for you to leave so that she can start her new single life, she can't do that with you in the house. I think you yourself mentioned that she got angry when you proposed that she move out and you would stay (it was either you or someone else in a similar situation).
She wants the separation. She wants you to move out. She is being nicer to you to accomplish that goal, when you leave the home, expect her to become a different person because she will be.
Men always think that separation is a time for both partners to review the situation, the time apart makes you grow fonder for each other,etc. That is a male mindset, that is what you believe. I can guarantee you that your wife has different plans.
