Don't rescue her from what she's feeling right now. She needs to experience this reality. This is what it feels like to break up a family. IMO, she should not get to reach out to you to comfort her......when she was the one who brought this all about. That point is what she has to face. She must deal with losing the man she didn't think she wanted for her H.
PURE GOLD right there, and SUCH a valuable peek into the wayward mindset for you, HP. Sandi, you are such a blessing!
