My guess is that mama June just doesn't believe her daughter and feels she made this up for some reason. Complete denial. If I were the daughter I would have absolutely no relationship with the mother.
I told the story of how my former best friend's husband molested my child. Thankfully, if you want to call it that, he only got to where he put her hand, while he thought she was sleeping, on his genitals. He did this twice. The first time she wasn't sure, the second time there was no question in her mind.
She told me immediately and I believed her without a doubt. To this day she talks about how grateful she was that I didn't question what she said. She was afraid that I wouldn't believe her, as I guess most sexually abused children are.
For that mother, and I use the word loosely, to believe the word of a child molester over her own child is unforgivable. I hope all her children are removed from her. She has given up her mother card.
When your child tells you she has been molested you believe that. Even if there is a 99% chance she is lying. You keep the child safe and you report the abuse. Even though we were told that he couldn't be prosecuted because there was no physical evidence (thank God!) my job was to make sure she never came into contact with the abuser again. I would have failed my main job as a mother had I questioned my child and not kept her safe. When it comes to abuse you always err on the side of caution.
My former friend told me that she refused to believe my child because if she believed her that meant she would have to leave her husband and she didn't want to do that. It was more important to this person to have a man in her bed then it was to protect a child she professed to love like her own, a child she was there for her birth and was another mother to. There are no words for that kind of person.
My daughter told me she felt guilty that a decades long friendship ended because of what she told me. I assured her that there was no way I could be friends with this person and she did me a favor by allowing me to see her true colors.
