Hey MJJC,
I wanted to share a different perspective about the allegations.
I am not a psychologist or an expert in this subject in any way, and this is merely my own speculation, but I see many similarities between the accusers behavior and statements, and symptoms of bipolar disorder.
There is a symptom associated with bipolar disorder known as erotomania, which is "is a rare disorder in which an individual has a delusional belief that a person of higher social status falls in love and makes amorous advances towards him/her." (Erotomania revisited: clinical course and treatment. Page 787) This person "is unattainable in some way, because he is already married or because he has no personal interest in" the sufferer, a "person with whom a relationship was previously established but with whom the person no longer or has never had contact with" (Page 789) Several patients with erotomania had delusions that "served as a defense reaction against homosexual doubts and feelings of competitiveness or resentment and may have been an attempt to incorporate power and self-image." (Page 791) A female patient had extreme delusions, such as marrying the man she pursued, getting pregnant, and even giving birth. She also said that the man "provided meaning to her life that she did not have before and if she did not have him her life would have no meaning." (Page 788) "Patients with erotomania who have bipolar disorder are more likely to have a recurrent form of erotomania" (Page 792)
The sufferer's "love is of sentimental kind, he is wholly occupied by the object of his adoration, whom if he approach it is with respect." Patients are unable "to put themselves in another person’s place and thus correctly assess their behavior and intentions. Thought insertion and ideations of control by others can be traced back to dysfunctional monitoring of one’s own intentions and actions." (Understanding delusions)
"An individual may believe that this person is communicating with them and affirming their love, using secret messages." (What is erotomania?)
"Stressful events in a person's life, such as a death in the family, can trigger [...] psychotic symptoms", "such as false perceptions (hallucinations) or strongly held false beliefs (delusions)." "People with bipolar disorder experience both dramatic "highs," called manic episodes, and "lows," called depressive episodes. [...] Manic episodes are characterized by increased energy and activity, irritability, restlessness, an inability to sleep, and reckless behavior. Depressive episodes are marked by low energy and activity, a feeling of hopelessness, and an inability to perform everyday tasks." Studies seem to indicate that bipolar disorder is associated with genes and could be hereditary. (Genetics Home Reference - Bipolar Disorder) "Bipolar disorder and alcoholism commonly co–occur" (Bipolar Disorder and Alcoholism)
