Taite also shared the same message to his Instagram page.
The couple fell in love on the 2018 season of the Channel 10 dating franchise, with Ali choosing Taite over Todd King.
The couple had planned to open fitness studio Sweaty AF in Ballarat, and each still promotes the business on their Instagrams.
Following Taite and Ali's split, Georgia Love and Lee Elliot remain as its only Australian success story. The Bachelor couples still together include Tim Robards and Anna Heinrich (who are currently expecting their first child), Matty J and Laura Byrne (who are now engaged and share one-year-old daughter Marli Mae) and Sam Wood and Snezana Markoski (who are married and share two daughters).
