Boyfriend is lying

M

I've been sober for 2 months now. My boyfriend and I decided to do it together since we both had a problem with drinking. In his birthday his friends had a party for him and when I showed up he was drunk and told me he'd never do it again and understood why i was upset with him. Well 3 weeks later I go to his house before he got off work and his brother points to the dresser. I open two drawers and they are full of empty beer cans and empty twisted tea cans. Plus a 6 pack half drank. He also has blood pressure issues and hasn't gotten on the meds like he is suppose to and this worries me with him drinking again. I'm so upset that he's been lying to me. I love him very much and just want the truth but I don't know if I can trust him even if he tells me he won't drink anymore. That he will just always hide this from me. I don't know what to do or how to go about this. Anyone have advice for me? Thanks.
