My ex (34F) and I (32M) divorced years ago because unfortunately I could not make things work. She has severe BPD. I had about 5 different counselors/therapists on this issue and tried to get through it for years. Even her family and "past" friends had reached out to me to confirm her BPD issue.

Fast forward to present day we are divorced and our 6-year-old lives with her. I get her every other weekend. I find out through my child, several times, that my ex is telling her very inappropriate things regarding our past relationship. Detail stories of infidelity and theft (which are not true). This is very concerning to me because weather they are true or not, its not something any child should hear. I tell my ex that its very inappropriate and that if she needs to talk about those kinds of things then she needs to talk to an adult about it, NOT our 6-year-old. Of course she does not deny it, instead admits that yes she talks to our child about these things and claims shes not in the wrong.

Has anyone else come across a similar situation like this? Where a child is in between one parent and a parent with BPD? I'm seeking any advice on how best to approach these types of scenarios and the best way to raise a child with a BPD ex. Thanks.
