Hi Dorabelle,
All of us on this board have Exes who are BPD, NPD, or have strong straits of this disorders, or are step-parents to kids whose other parent has the issues. You'll find a lot of support here
To start, can you tell us a little more about what's going on? How old are the kids, and what are their biggest struggles? What's the living situation like?
You might want to take a look at the lessons to the right of the board, particularly lessons 1 and 5.
