Pep123,
As an ex Teacher and Cocaine user I’ve had some experience in your situation so I can give you my version if it helps. I have to say that without getting some professional help for him then unfortunately he’s going to continue taking but I’m sure you already know that but what you can do is start by giving him some options. His ultimatum is he must attend regular drug counselling and especially agree to screening/testing on his urine. Yes it sounds extreme but it’s the only way to get some commitment from him with regards to the children. It’s a sure fire way to gauge his commitment to get clean. Cocaine is fearlessly addictive and basically prevents you from telling the truth to anyone you love and both me and my fellow addicts would have dug up our dead grandmas and sold their bones just to satisfy our addiction! He will never stop this on his own and I can guarantee that so please be super strong and strict when you sit down and give him the ultimatum. I nearly lost everything I loved and yet lost the one thing I loved more than everything, and that was Cociane I’m afraid. I love my child and wife and now I’m free but one drug can easily be replaced by another so voluntary drug testing and good professional help is your best option. Otherwise, if he won’t agree to help for the kids sake, Drop him like a hot potato. Take care
