My best frend's parents and my sister have both been in this situation. In both situations the Mom said, "Get out" and so the girls did. They packed thier things and said, "I'll be at -------'s house if you need to contact me. They have offered me a place to stay."
In both situations, the mom's just let them leave. Hardley ever called, and my sister and my friend's mother were happy to have a new family member.
You may think this risky. The parent could come in at any time and demand back their child. Luckily that didnot happen in my experiences. In both situations the girls came to live with the other families at about 15 yrs. old. And both families saw these girls off to college. Which was a priority in the household. I doubt she is getting that same expectation where she is now.
My opinion. It's worth the risk. Get her room ready. Tell her it's ready when she is. Offer to speak to her mother with her. Explain you "can understand she may be feeling overwhelmed and would like to help out." Maybe even tell her to visit her daughter whenever she likes, but she would really be doing YOU a favor if you could bring this girls into your home.
I guess there are 2 reactions you could get back, relief, or offense. If you think you getting into the conversation would make it worse for the girl, don't be involved in the conversation. I hope this mother really does want her daughter to find another place and doesn't just want to have her daughter crawl back to her when she can't find one. But people don't usually say things unless there is and incling of the truth behind it.
Go for it!!
