Long story short, my husband was recently awarded temporary sole custody of his kids. It has been a very messy and toxic situation with his Ex ever since we started dating, and that was over 10yrs ago. I want to believe she is a good mother but not a good influence when it comes to the kids. The kids were removed due to environmental neglect and mental abuse. She has been involving them in adult situations for a few years now, meaning whenever her and my husband would have an argument or a fight, she would tell the kids everything about the situation.
