Tonight, when we were having our talk about me being suspicious that he was smoking, he admitted to me that he smoked pot with his aunt. He was scared to admit it to me because he knows I would be mad at her. He made it a point to tell me he chose to do it. I explained to him that she was the adult (35 years old) in the situation and it never should have happened.
I just texted her and said:
You would think after losing your own kids because you couldn't stay clean that you would be smart enough to not contribute to a minor. I knew better than to trust you with my child. Do not contact my kids via phone, FB, or otherwise or I will report you to CPS and the police. That is if I do not decide to do it anyway. It is in your best interest to remove them from your FB. You will be lucky if I do not report you.
She has not responded.
