Hi Hurt&Angry,
It is a pity that the children had to be separated. I was hoping you had them all.
What combination did you have together? What ages? what are they saying?
I think it is a shame that courts spring into action to protect property but are slow to intervene in "domestic" problems.
If you think about it, the only reason you were able to get this done (only first step but big one) was because of your living arrangements. The sad thing is, the children get separated and hurt because of an addiction of an adult in their lives.
I am sure you realise, this is no picnic for her either, but the family cannot be subjected to this crap while the addict recovers.
Enjoy the peace, and do work with her family to find a solution, where her child can come over for sleepovers/playdates with granny or something.
Hugs
