Sipho and Siphokazi began working as telemarketers at an insurance company on the same day, and two weeks later ,

they started dating. Siphokazi constantly monitors Sipho at work and does not

like it when Sipho engages in light conversations with female colleagues in the

office. Siphokazi is convinced that her female colleagues are “after her man”,

which makes her feel threatened. Siphokazi tends to follow Sipho wherever he

goes. This makes him uncomfortable as he no longer enjoys interacting with

colleagues. One day, she accused Sipho of “taking too long in the bathroom

because he needed privacy to speak to one of his girlfriends”. Siphokazi made

it clear that Sipho is not allowed to have the phone numbers of female colleagues.

Hence, she constantly browsed his phone to check his call records, texts and

WhatsApp messages. Recently, Sipho realised that some of the important contact

numbers had been deleted from his phone, and when he asked Siphokazi, she

denied it, even though she had deleted them. Sipho and Siphokazi share the same

telecentre office. On one occasion, Sipho was laughing on a call with a

potential client, and Siphokazi accused her of flirting with clients. This made

him upset, and he decided to end the relationship with Siphokazi as he could no

longer keep up with her unreasonable jealousy and embarrassing stalking

behaviours.

If you were the Clinical

Psychologist managing Siphokazi's case, how would you classify her behaviour

according to the DSM-5-TR classification system?
