Don't delete her rants. Six months from now she truly will not remember what she wrote or will minimize them. Read this and then re-read her rants.
Short version of DARVO*
DARVO refers to a reaction perpetrators of wrong doing, particularly sexual offenders, may display in response to being held accountable for their behavior. DARVO stands for "Deny, Attack, and Reverse Victim and Offender." The perpetrator or offender may Deny the behavior, Attack the individual doing the confronting, and Reverse the roles of Victim and Offender such that the perpetrator assumes the victim role and turns the true victim -- or the whistle blower -- into an alleged offender. This occurs, for instance, when an actually guilty perpetrator assumes the role of "falsely accused and*attacks the accuser's credibility or even if the event occurred. * **term "DARVO" near the end of a 1997 publication about her primary research focus, "betrayal trauma theory."*
"By denying, attacking ' *and reversing perpetrators into victims, reality gets even more confusing and unspeakable for the real victim. .... These perpetrator reactions increase the need for betrayal blindness. If the victim does speak out and gets this level of attack, she quickly gets the idea that silence is safer." (Veldhuis & Freyd, 1999. p 274).
It didn't happen (an instance) or It rarely happens (a type of event)
It wasn't harmful *Put together they can take the form: "It didn't happen, but if it did, it wasn't that bad" or "It rarely happens, but when it does it isn't harmful." The two claims both serve to deny, but they depend upon different sorts of evidence. They may both be true, but they are sometimes somewhat suspicious when claimed simultaneously (or by the same person at different times), as for instance can occur in response to allegations of rape or child sexual abuse.
