AITA for exposing my husband after I found out he was secretly sabotaging my business?

I (32F) have been married to my husband, Daniel (35M), for seven years. On the outside, our life seemed perfect—we had a beautiful home, two kids (Ella, 6, and Max, 4), and I ran a small but growing graphic design business from home. Daniel worked in finance, and for years, he was my biggest supporter. He used to tell me he was proud of everything I accomplished and always encouraged me to chase my dreams.

Over the past year, things started to feel off. My business began to stall despite my hard work. Clients I had been working with for years suddenly canceled projects or stopped returning emails. I thought maybe it was just bad luck, but then I noticed something strange—Daniel would ask me about specific clients and projects, even the ones he “shouldn’t know about.” I brushed it off at first, thinking he was just curious or trying to help, but a part of me felt uneasy.

One night, while I was preparing a presentation for a major client, I overheard Daniel on a call. He was speaking to someone in a hushed, hurried tone. At first, I didn’t recognize the client, but as I listened, I realized he was calling one of my biggest clients, giving them false information about my services and claiming that I was “overbooked and unreliable.” I felt my stomach drop. How could he betray me like this?

I confronted him immediately. Daniel initially denied everything, saying I must have misunderstood. But I had proof. Emails, screenshots, and even recordings from my own calls showed that he had been secretly sabotaging my business for months. He claimed he was just “trying to protect our family finances” and that he “didn’t want me to overwork myself,” but the truth was worse—he was jealous of my success. He couldn’t handle that I was building something on my own that was thriving.

I was devastated. Not only had my husband betrayed me, but he had also deliberately tried to destroy everything I had worked so hard to build. I couldn’t believe the person I loved and trusted could go this far. My heart felt broken and my trust shattered.

After gathering evidence, I confronted Daniel again and told him I would have to take action to protect my business. I informed my clients of the situation and made it clear that no one was allowed to speak to him about my projects anymore. I also spoke to a lawyer to understand my options regarding our business finances and ownership. Daniel was furious. He accused me of humiliating him and said I was overreacting.

The fallout has been intense. Our marriage is on the brink of collapse. Some of our friends think I overreacted and that I should have “worked things out privately.” Others tell me I did the right thing because betrayal like that cannot be ignored. Daniel refuses to admit that what he did was wrong, and I can no longer trust him around my work, my clients, or even my own children, since I feel his judgment is clouded by jealousy and resentment.

I’ve started taking steps to protect myself and my business legally. I’ve also started considering separation, because living with someone who has betrayed me so profoundly feels impossible.

So, AITA for exposing my husband after I found out he was secretly sabotaging my business?
