Just be happy someone else is happy. I am so excited Julian gets to grow up with a sibling as I grew up as an only child,' she wrote.
The reality star also reflected what her time spent on the Seven show taught her.
'Beautiful moments, funny moments, upset, sadness and heartache,' she wrote.
The couple’s relationship came to a dramatic end on Monday night’s episode of the show, with Milly confessing to having huge doubts about their relationship after the explosive lunch with her mum Catherine and Micah’s mum Deirdre.
“Micah and I are just not in a good place now and it’s all fallen to pieces in the last few days. I’m not OK and I’m not coping,” Milly said.
Micah added: “I am sick of Catherine. She finally got what she wanted, and she has driven a wedge between us a few days before the wedding. That lunch ruined everything.”
Milly eventually ended up calling off the wedding after revealing she was worried that his use of alcohol and marijuana would be a bad influence on their son Julian.
She said in a piece to camera: “He's not well and he needs a lot of help and I feel for him because I do love him, but he's just really not made progress.
“And I thought he had. I'm so sad because I don't want Julian to grow up to be like that. He just doesn't need a role model like that.”
