I am sorry you ran into a freight truck! Good job dodging the bullet. Your W is angry at something and you are likely to be a target for a long time. This is a testing time for you and I wish you strength in staying calm through the storm. This flurry of anger is perhaps your W's guilt and self-loathing reaching a crescendo. Let her fall.
If you look at the MLC Forum you will find some very good discussion by some very good folk on Oh_so_blue's thread. I must warn that there has been infighting there but it is revealing nonetheless.

The 3 laws of DBing:
1. PMA is critical to DBing.
2. Since drop in WAW's PMA leads to drop in LBS's PMA and vice-versa detachment is critical.
3. Validate to raise WAW's PMA and GAL to raise LBS's.
