Well, that sounds impulsive. Sorry she's up and taking her daughter and moving to another state. To figure out what she wants? Doesn't seem, like it's all about you and her, as a couple, clearly she has lots to sort out in her own mind. Just stinks that you are left with the emotional fall out of this.

I wonder, if the give her time statement, is less about give her time to want to work things out with you, but more time for her to come to her senses. ( I say this, because parents moving across state lines can be risky business, without some sort of legal approval)

Hope you are able to heal through your grieving process.
