I've thought about what I would do if my X's old sugar daddy kicked the bucket and she was up a creek without a paddle. I would not take her in. The fact that she is my kids mother does not play into it. I would not want to open old wounds as it appears have just been done to you.
I dont know if you should concern yourself with shielding your D12 from the true nature of her mother. It just seems like a lie or a cover up. Likewise, you should not say anything bad about her mother. Your D will eventually find out over time on her own that her mother is a habitual adultress and that would be an issue between the two of them.
