My DS (18) confessed to me last night that he smokes. Of course I was disappointed but he's 18 so he has a right to make his own life choices. What REALLY upset and annoyed me was, my ds told me that he told my DH August 2017 and ever since then my DH has been buying him cigarettes with our money, behind my back. So he's not just kept this secret from me but has been going behind my back on a daily basis for over a year now! AIBU to feel like I can't trust him anymore? Note: this isn't the first time he's lied to me. I'm so confused. I would never keep secrets from him especially about our DC. I feel like I don't even know him anymore.
