FY, I'm so sorry that your w is in so much pain. She's got to work thru it and it appears she is. I think it's a wise idea to stay back and let her go visit her father today. She needs that time w/him today.
Give her plenty of space and be there as a friend. She's got some issues that will need to be heard very soon. She's going to need a good listener and you will need to truly listen and be there to validate, but don't try to fix.
The holidays are bad for both the mlcer and the lbs. However, I do think in some cases the mlcer may have it a bit worse than we do.
Hang in there.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
