Advice for telling kids stuff

[paularubotham]

How do I tell my 12 year old some that his dad used his lie about why I wanted him to speak to those nice police to gain custody of both my children for a year

How do I also tell my 7 year old daughter that only trusts me to open up about the sexual abuse masturbating by her father to others. He lied in Court and said it didn’t happen it didn’t even answer to me both my kids open up last week saying they didn’t tell social service as they thought I would go to jail. The also didn’t like the social worker non of us did
