I am new here and am inquiring if anyone knows anything about Schizoid Personality Disorder. I was involved for many years with an individual who seemed to have no interest in me as a person, didn't know how old I was, didn't know when my birthday was, didn't care anything about my background, etc. I kept blaming it on myself, but I am wondering if he could have been Schizoid? I could never figure out how someone could be so disinterested. Thank you in advance for any insights.
