When Carlos first began to date Jenna, their relationship escalated quickly and became sexually intense. However, after a couple of weeks, Carlos became increasingly uneasy because Jenna seemed to need his attention constantly. Jenna would text and call him 20 times a day and became furious if he did not respond immediately. When Jenna showed up unexpectedly at Carlos's office to have lunch with him, she became enraged and tried to hit him when he told her that he was taking two important clients to lunch. The next day, Carlos tried to break off the relationship with Jenna, and it turned into an ugly scene in which she screamed profanities at him. Later that evening, she texted him a very long apology, taking the blame for all of their problems. Several days later, Carlos learned that Jenna had been hospitalized for overdosing on tranquilizers and alcohol. Jenna's pattern of behavior MOST likely fits disorder.
