AITA for deleting my boyfriend's online chats?

I got access to my boyfriend's hidden links and forms on Google and MS for online porn chat rooms and deleted them. On one occasion I logged into a scheduled meeting as him and started sending funny emojis, and the chat ended immediately. He said his account had been hacked (since hackers just love to use random accounts for chatting only), and kept getting upset when I confronted him. The part I feel bad about is that he has been depressed and nervous. He obviously knows that I know, which makes me feel bad since this is probably a serious addiction issue, and he is too embarrassed to talk about it with me. Now I feel guilty for messing with him. I know I should just break up with him since he doesn't seem to want help. I feel like I am being just as toxic and enabling him to continue self destructing.

I should have also added that he hasn’t been in the mood for almost a month but he’s always had a lower libido. I happen to think that some people prefer porn.

Update: I realized this is a manipulation tactic he does by withholding and watching me go crazy finding his accounts. I also read his emails to several exes and he did the exact same thing!! I hadn’t realized that since being with him I lost all my friends, quit a good job, and rarely see my family. My daughter has been depressed and I stopped taking care of myself. I broke up with him and asked him to move out. And of course he brought up the online accounts. That’s the only thing he has on me. And now I have no idea how to get him out of the house. He’s never going to leave and I’m also kinda scared.
