Life is about choices, you can either choose to drive your car or ride in the back seat.
This is up to you, if you want to be the driver, don't read his text messages, just delete them and don't answer the door.
This is a choice only you can make.
He is an adult, he will make his own choices, whether you answer the door or you don't. That is one of the hardest things for we codies to understand, no matter what we do or don't do, they will do what they want to do. We cannot control their behavior.
They do understand what is going on, they just choose to continue using and not embrace recovery.
