You know this happened with my daughter and her father in the past. She went to therapy and it helped so much. Also the father went to therapy and learned how it is damaging to a child to instill doubt in them about either parent.
I read you already have your child speaking with a school counselor, but what about a private therapist? Usually they like both parents to attend and you may be able to solve this issue in therapy.
I would not eavesdrop on the child, it's bad enough one parent is being damaging. The child doesn't need to then have the added weight of invasion of privacy. Then the poor child will have a vindictive mother and an intrusive father, and where does that leave the child? That's just my opinion.
