That said, I would quickly, make plans for Saturday night. Tell her that matter of factly that you need to go out with your boys, or whatever. Even if no one can go out with you, go out by yourself, go to the gym, but make it appear that you are too busy to go with her anywhere until she is ready to speak. You can even ask her if she can watch your daughter and if she can't, maybe the two of you can do something special. I swear to you with how she is acting it will not take her long to start to "spill the beans".
Go through Puppy's list and follow it. This is going to be very hard, but I guarantee you it is the right advice. Be strong, you can do this!
