Are there any success stories out there that started off in a high conflict/antagonistic situation?
It’s been over a year and a half post divorce and coparenting our five-year-old. The post separation has become significantly worse for me and more importantly our child. Ex is in contempt for breaking the parenting agreement. Sends page long messages, disparaging me, making false accusation and is obsessed with my new partner. Has had a private investigator, has made false claims about me and my partner. Uses the child as a weapon, manipulates, loyalty, conflicts. Tens of thousands of dollars in court fees.
Has anyone successfully got through this? What happened?
