Cyrell took to Instagram to share a photo of her and her bump and confirm the break-up in a lengthy Instagram story.
She also took to her Instagram story to write: "You would think people would be happy to hear about my break-up. Are you all not happy? Was this not what you all rooted and prayed for? Or maybe your prayers of me having a miscarriage is what ur hoping for next?
"We live in a sad, bad world where [we] wish and pray for misery on others to feel better about ourselves.
"I hope this shows a reflection of the weak, sad individual you are. I may not have a partner but my son is all I need."
Cyrell has also deleted all images of her and Eden from her account and they have unfollowed each other on social media.
The pair were forced to reunite recently due to a defamation court case.
The estranged couple were spotted in Sydney, where they both faced a court hearing into a defamation claim.
The claim has been made against Cyrell and Married At First Sight's broadcaster, Nine.
Cyrell is being sued for $50,000 by the Pelican Cafe Takeaway for comments she made following an alleged altercation with owner Deborah Wilson.
