I think "shock" is an understatement, it's only been 30+ days!!!
The truth is she left confused and still is. She left in haste. She could not have possibly thought it through completely, all the consequences for everyone involved....especially for you and the kids. Does she realize she is opening the wounds?
I would be cautious that she is now alone and has no where to go thus the turn towards what she had and must still believe could be available to her.
I know you still love her. You have to search your soul and decide what you want now. It will be very hard.
What has happened over the past three days?
It is possible she is truly sorry. It is possible she can turn a new leaf. It is possible with open, truthful communication the marriage could re-unite with time and patience.
I think it best for a chat and lay it on the line, tell her the damage she has caused to you and the kids. Make her be accountable for her devastating choice. Tell her you were moving on. Ask her what would be different now. Tell her that you will need to think on her replies, make no promises. Let her pursue you.
I am intrigued that this has happened so soon. Part of me wonders, if the time she had away she also honestly realized what she really wants was what she had and threw away.
This is very interesting.
I wish you well, and hope you keep us posted on updates.
Take care of yourself right now. I can imagine the turmoil this is causing for you.
