Mine did the opposite: she unfriended all of my friends on FB (much to their chagrin and offense) and then convinced her family and friends to do the same.
Same here. I logged on and over a few days I noticed all of her family and friends unfriended me on FB without a word.
Some of my family members commented that they were surprised that she didn't say goodbye and simply unfriended. I was split black.
That being said ta777 I get the impression there's a lot of drama with her and your friends. You know your situation best and I do get the impression she's seeking attention. Negative attention is still attention.
