Hi there. My ex is a drugs user I can confirm he was using occasional crack and all the time pot when we were together. I now believe he is a heavy user of some sort of hard substance. His behaviour is erratic and unpredictable and always very aggressive. He was admitted to hospital yesterday after being very intoxicated and suicidal and involved in a physical altercation with his dad trying to get our daughter. I have always believed he would put the kids first despite his many issues and that they were safe. He agreed to stay for the psych evaluation but then discharged himself. It is not known whether it was actually completed. They are due to go to his house tomorrow for the weekend. I am now concerned for the kids' wellbeing in going there this weekend after everything that has happened and his state of mind. So my question is, what rights do I have to keep the kids away until I feel comfortable that he is mentally stable enough to have them again? I'm not looking for permanent family court orders to keep the kids away as they really do love seeing him, but for now until I think the kids are safe.
