I'm sorry, sweetie. This happens during all of this. She is trying to reconcile what she needs to and that includes where she is at in life and what she wants it to look like moving forward.
They have to go back through all the phases and shut the door on them for good. Its not a picnic for them or for the spouse.
Seems like she is going back a bit into anger and blame.
Give her some space to work through it.
And remember, you are human. Sometimes we just have to be honest regardless of what it may bring.
