I have a promiscuous friend.....?

A girlfriend of mine is unhappy in her marriage. She has been with her husband for seven years, married for five and cheating for three with multiple people. She has not just had one affair but numerous ones. She has been involved with married men and has tried to pursue married men. She partied on the weekends for nearly a year leaving her kids at home with the husband...who never knew of her promiscuous ways. She would tell me that her husband did not give her enough attention and didn't seem to care about her. This past Sept. the husband found out about one of the affairs. They had been battling divorce talk over the course of the past few months. After sept. she has started dating another married man that she works with whom is leaving his wife. She says that out of everyone she has dated this is her true love. she says that she has searched her whole life for this person. She told her husband that she is in love w/ him and they are going to get a divorce.
