Drained u said your not strong enough but u will have to find the strength. Put all that energy and strength into helping u and your kids instead of trying to convince him he has a problem and needs help. Take the focus off of him and his addiction thats what u really need to do. Everything else concerning him is out of your control and no matter what u cant control it. Drugs may bring out some things in people but something tells me thats always been there its just coming out more cause of constant accusations and constant questioning in search of answers. I didnt like being pushed or asked questions. Especially questions u already know the answers to yet u want to hear them from him. Guess what you never will. Stop playing detective stop focusing on him. Start focusing on u and your children once the focus is off of him and on u watch how good u start to feel.
