My boyfriend did the unimaginable.

This is incredibly vulnerable for me to talk about, I feel absolutely sick to my stomach and I can’t even cry anymore. I don’t know what to do. My (19F) soon to be ex boyfriend (19M) was the love of my life. He was my life for 3 years, and now I’m completely lost. I am breaking up with him tonight, and I am so sad and lost but I know it’s what I have to do. He was my best friend, and I can’t believe who he became. Around May of last year, I caught him sexting an AI chat bot on snapchat. I looked through his phone while he was under the influence and sleeping, I felt bad about doing it but his phone was blowing up. I opened the chat, and I saw pictures of him doing extreme sexual things while sexting this chat bot. He is bisexual, or he would like to say unlabeled. He was basically sending videos of himself doing things to please this chat bot. I scrolled up further, and I saw nudes of me. This is what caught me off guard, I didn’t know who could be seeing this. I know it’s an AI, but who knows where that stuff goes? I’ll get more into that after some more details. I forgave him, stupidly, and brushed it off as bad judgement. Then, in November, He asked me to update his GPS while he was driving. I did, and then checked his snapchat because he got a notification. I saw a different chat bot, asking him to meet up. So I assumed it could’ve been a real person? I doubt it, but it’s something I’ll never know. We got into a huge fight, he promised he would never do it again, and we slowly moved past it. This February, I got a message in my inbox on instagram. It was a dude, telling me that pictures of me were leaked on twitter. I didn’t believe him at first, so I asked for proof. And there it was, My full name, address, naked pictures of me, my age, my weight, all plastered on a twitter page. I feel so disgusting about myself, knowing that I’ve been exposed to who knows how many people. We’ve been in a rocky spot every sense, I am unable to forgive his excuses and lies. He claims he was texting ANOTHER chat bot and the bot made a twitter to expose me but he didn’t know that. I don’t know if I buy that. Now, March, I decide to log into his snapchat. He previously gave me his information after the last event to try to build my trust. I told myself I’d never look. I woke up this morning with a sick feeling in my stomach, I think my body knew something horrendous was going on. I logged in, and saw the first original chat bot. I clicked on it, and minutes prior he was sexting the bot, during his break at work. I became furious, and then decided to look at everything else. I then saw the most disgusting things i’ve ever seen. Naked photos of my sister, my friends, his exes, and random girls ALL AI GENERATED NAKED. As well as, me. Real nudity, and AI generated. The grossest part was that there was a picture of me and my sister in 8th grade AI generated into us naked. WE WERE CHILDREN IN THIS PHOTO. WHO KNOWS WHAT ELSE HES INTO? I told him what i found, and he explained he was aroused by doing “bad things”. I told him it’s over, and that i’ll collect my stuff tonight. I am going to make sure all of these photos are wiped from his phone and computer. I feel like I need to tell all the girls he AI generated about this, as this is disturbing and who knows where these photos are going? Twitter? A real person?!?! I am beyond heartbroken. I can’t cry, i’m just disgusted. I don’t know what I did to deserve this. Is there any way I can go to the authorities? I know it AI and it’s probably hard to be used as evidence, but I feel unsafe and worry for others safety. I hate myself for forgiving him again and again when he’s shown me nothing but his disgusting actions behind my back. I want to email his work, he’s an EMT and I feel like this isn’t someone who should be serving the population. I don’t know where to go from here. I loved him so incredibly much, he was everything to me. But all of it was a lie. I know most people will make fun of me for staying, but I genuinely thought this was forgivable at first and that it wasn’t “cheating” since it wasn’t physical. But this isn’t cheating, this is concerning behavior that my mind can’t even wrap around. Please give me advice, I am a young girl struggling with being an adult and this is the worst i’ve ever felt in my life.
