Marijuana and 14 year old son - I don't have custody
I obtained evidence of my 14 year old son smoking/vaping marijuana and selling wax pens, by invading his privacy and logging into his account. I have not lived with him since he was five years old. I have no custody. Our interaction is limited. How can I bring about this evidence to the father, so that he can place rules upon our son? As currently, father travels and son has free range. Also it is essential this does not break my already fragile relationship and trust with my son.
