Thank you everyone for your feedback.
I caught him in a lie today and explained as nice as I could that he is not being truthful and I didn't appreciate it. I also took it further and told him that is why we aren't living together anymore because I get exhausted trying to decipher his words.
I was getting so flustered that I ended the call. To many topics in one conversation for me.
I can honestly see how drugs and alcohol can change the chemical balance in a brain for the worse. How he can't understand what a lie is.
I've been going through this nonsense for so long I can't imagine what a normal conversation would be with a mate
