My ex de facto partner has been proven by NATA accredited DNA testing not to be my Daughter's biological father even though he has been in her life since birth (I had an affair). We have been separated for 2.5 years, we were together for 3 years of her life. She saw him alternate weekends when we initially split up but the she came home and alleged child abuse. I followed the DCP, police and family court procedure and the allegations were never substantiated due to her being so young. He has been having supervised visits for 2 hours every 4 weeks. He is now fighting for shared parental responsibility however for 2 years hasp my seen her in a supervised setting, has paid no child support and left the family home without contributing a single cent to the process. He started the court journey, we've failed mediation, there's a VRO ( restraining order) in place that he's been charged with breaching twice. Please help!
