I remember a member here from a few years back, she had spent a year in jail and lost her children because she had answered the phone and taken a message for her addict husband to call someone (who turned out to be a dealer). Something that simple, and sadly normal in the events of a day for someone living with an addict...changed her life forever. She was charged for "knowing" about the criminal activity that was going on.
Driving to drug deals, however unknowingly, could put your life and the life of your children in serious jeopardy.
You don't have to be right about everything you think he does or doesn't do. He is actively using drugs, you know that and that's enough.
What you choose to do about it may change your life and the lives of your children forever...for better or for worse...the choice is yours alone.
My heart hurts for you, I know this cannot be easy. But I worry for you too because I have seen where this kind of thinking can take you and it isn't pretty.
Hugs
