While I am sure it hurts, but is there a chance that she can join another House?
While it may sound crass, things do happen.
One of My own low number Brothers (54) joined a Fraternity across the steet from ours.
We all got over it and He was happy so all was good.
As some have said, COB or I think a new wording COR is still a posibilty.
The best of Luck to your daughter.
