I just broke up with my partner of 10 months because he broke my trust.

He didn't cheat on me. He relapsed and he didn't tell me. He said something that made me suspicious and after that I told him we needed to talk in person. When he came over he ended up confessing to relapsing a couple of weeks ago. He didn't come clean because he wanted to,I essentially caught him. I can't trust him. I've learned from my mistakes. Matthew 25:21 “"His master replied, ‘Well done, good and faithful servant! You have been faithful with a few things; I will put you in charge of many things. Come and share your master’s happiness.’" I gave him my trust,he was not faithful with it so I cannot trust him with more. I can't continue to give him the benefits he had before he betrayed my trust. My problem lies in the lie. I'm fucking devastated but I am proud of myself for choosing myself. I love him dearly and I wish him the best. I hope he heals from his addiction. He was an amazing partner but I can't let that cloud the reality of the pain I'm experiencing because of his choice to lie to me. Had he come to me the first time it happened a few weeks ago then I would've supported him,it's the lying that I can't forgive. Again I'm devasted but better now than later when his addiction can have even greater negative effects on me.
