Is your advisor from your chapter and the same age as these women? If so, she may be the one they're mad at, not the actives. If the advisor is someone that the majority of the alums do not like and won't get behind, you might need to take actions to relieve her of her position. An advisor is supposed to be support not something else to stress over.
If I've totally misinterpreted the situation please correct me!
