I have divorced a little over a year now and have joint custody. My six year old son said my ex's boyfriend...

Touched him in an inappropriate place and my 11 year old told me he yells at him and has caused him anxiety. What the 11 year old told me has been back up by the school. I reported him to the proper agency. I just do not want my ex to think it is a personal attack on her. I even told the agency it has absolutly nothing to do with my ex wife. Any othe suggestions to make sure the focus is only on him and to keep my ex wife out of this. Just becuase we got divorced I do not believe in hurting someone for an unfounded reason......
