headcase 

A person that is impossible to date due to numerous psychological disorders, offensive personality traits, or unresolved psychosocial trauma.

When we first started dating, I was able to deal with his extreme passivity, unwillingness to drive at night, never wanting to have sex, fear of adhesive tape, and never answering questions about his personal life. I finally dumped that headcase when I found out his current roommate is his ex and they still have freaky bondage sex together.
