Neighbours ' Dipi Rebecchi (Sharon Johal) is feeling incredibly guilty after starting a steamy affair with Pierce Greyson (Tim Robards) behind her husband Shane's back.
Things between her and Shane have hit an all-time low after he finally came clean about his drug addiction before claiming that Dipi was the one who drove him to taking drugs.
Seeking comfort in Pierce, the pair started confiding in each other as Pierce's own marriage to Chloe Brennan (April Rose Pengilly) has started to crumble after her tragic miscarriage.
Both of the married couple have been feeling very lonely, and seem to be growing closer at a quick rate, hinting the pair could be developing secret feelings for each other.
Fans know that things have escalated between the pair, and they have started seeing each other behind their partners' backs.
But Sharon has hinted that the guilt will become too much for Dipi, and she could be set to come clean to the pair about the infidelity.
Speaking to Daily Star Online, Sharon said: "Every time she sees Chloe and Shane she feels disgusted with herself for what she has done.
"Seeing Chloe and not saying anything feels awful to her.
"She and Pierce tell themselves that it was an accident, and she is desperate to come clean to Shane but Pierce convinces her not to."
She continued: "She is feeling shameful and disgusted about what they've done, but then she does also feel like there is a reason why they're doing this.
"But then she feels like she deserves happiness as well and she is finding that with Pierce.
"But in reality, I think she is in actual extreme turmoil the whole way, you can see she is a shell of herself, she feels terrible."
Will Dipi finally come clean about her betrayal with Pierce, and how will Shane and Chloe react?
Sharon previously hinted that Shane could be pushed to a relapse if he discovers that his wife has cheated on him with his friend.
Could this end their marriage for good?
