Completely agree with Steve here. I will also add: do not try to reach an agreement with her. She does not want to agree with you. She is looking for disagreement. That justifies her decision to leave. Avoid confrontation and concede where it is not critical, and take the reins and act on your own where it is critical to do so. Trying to reach an agreement is pointless. She wants to take a favorite painting, CD or book that are yours? Give it to her. She wants to keep a joint account while having her own independent life? No thanks. You do not have to justify your actions, just do what is necessary to protect yourself.
