After eight years together, Tobi and I have come to the difficult decision to separate as a couple. We will always be family, and remain good friends and devoted parents to Arna. We have grown up together in Adelaide, sharing a lifetime of experiences and special memories from moving into our first apartment and starting SWEAT from our lounge room to becoming parents to our beautiful daughter. Our friendship remains strong as we parent Arna together and run SWEAT as business partners. Thank you for your support and kindness during this time.
