So this. My kids father that I’m separated from has relapsed after about two years clean - heroin and crack. I think I should tell my kids. They’re aware he has mental health problems but not aware of previous addiction issues as last crisis they were a lot younger. I think they’re old enough now to understand a bit 14 and 10, they already feel his behaviour has changed recently plus I think I am going to have to say no to contact again as he is actively using. How do you tell children about this? I know they will find it frightening. Posted on Addiction board but posting here for traffic.
