You're asking a questions about diagnosis, and it is inappropriate (and unethical) for a Licensed Mental Health Professional to make a diagnosis (a) over the internet; (b) across the country; and (c) about a third party without having seen him/her.
That being said, and with the understanding that we are not providing a diagnosis, the other feelings/behaviors you describe are delusional in nature. These types of delusions can be related to underlying thought disorders or, in some cases, severe mood disorders (like active, severe Bipolar Disorder with psychotic features). These delusions are not typically seen among individuals who manifest OCD or Borderline Personality Disorder.
I hope that helps.
