This is a whopper. We are dealing with a high conflict/avoidance BM here. Basically my SO is at her mercy, at least it feels like it. They have two children together SS(13), SD(11). We've had SS living with us full-time since the end of 2017. There was a spoken agreement that child support would be terminated completely since each parent had a child full time. Child support has been adding up and the BM has been dragging her feet for the past 3 years to file anything with her lawyer to put this to a stop. Excuse after excuse.
