The actress revealed that the upcoming arrival of Kirsty's father may help to show the police officer's behaviour in a new light.
Kirsty is about to take centre stage in a dark domestic violence storyline as she lashes out at her kind-hearted fiancé Tyrone Dobbs.
Gumede, writing in her itv.com blog, commented: "The tragedy of Kirsty - and perhaps a lot of people with a personality disorder like hers - is that she has so much going for her, and could be a nice person if she wasn't so damaged by her past.
"She has already explained that her jealousy issues stem from the betrayal of her boyfriend having an affair with her best friend, and in upcoming episodes we will see the arrival of Kirsty's parents.
"There is a very clear correlation between her father's behaviour towards her, and her behaviour towards Tyrone - therein the circle of abuse continues."
Gumede added that she is keen for Kirsty and Tyrone's storyline to have a positive impact in the weeks ahead.
She said: "Our safety is a basic human right, and one that we take for granted unless that human right is breached. Alan and I are able to leave Kirsty and Tyrone on set at the end of the day, but this storyline will hopefully raise awareness for those who aren't so lucky."
