Yes putting him in his place would feel good.
But, I also feel like by not saying anything in a way it is kinda like avoiding it????? I don't know I am the worlds best/worst when it comes to denial. It feels kinda like denial in not saying anything.
It is so hard! I feel the right thing would be not to say anything. I know he is using. He knows he is using. So what is the point of him knowing I know. Maybe he even knows I know.
