Caught my Bf selling my old nudes.

This morning I caught my(21f) boyfriend(21m) of 3 years selling my nudes.

He woke me up and passed me his phone unlocked. I was confused but i think he wanted me to put it on the side of the bed for him so I took it. I wouldn't have even gone through it if the app Kik hadn't been open. We had a "misunderstanding" last year when I had gone through his phone and found old videos/nudes of other people. He said they were strangers off of Kik that he downloaded and that he hadn't used the app since he was in middle school (the images looked to be grown women, just super grainy and old looking). So he forgot about them then deleted them on the spot when i confronted him.

So obviously having an app he said he had deleted ages ago caught my attention. I went looking and it was regular porn and chat boxs. None of that bothered me. However I saw a man named Erick in his chats and I looked at the history. The only things there were 3 of my nudes. In all my face is semi hidden. I was in shock. I got out of that chat and he had another one open called, Wife's.gf.(and something else i can't remember). Erick had given him access to this giant chat log of porn/nudes from strangers. I have no idea if the content on there was consensual all i know was that i wasn't consenting.

He had traded my pictures for access to theirs. My pictures will probably be added to the pile.

I woke him up and confronted him. I cried. He cried but was mostly in shock. He doesn't remember giving me his phone since he was half asleep.

Checking the time stamp he traded my nudes about 4-5 months ago.

So far, I told him that I personally can't stand being around him now. I hate his touch and presence. That my trust is completely broken. However, I have no money and he controls all the finances. Especially right now because I'm currently in training for a part time job. So i told him I'll stay if he wants me to but if he wants to interact with me at all he has to treat me like the whore he thinks I am. He's going to pay me $1,000 per nude he sent and any physical touch he wants from me he has to pay me. I'm doing this in hopes i can save enough to be able to leave without ending up homeless.

He wants to fix things, has apologize profusely, and has cried a lot. I'll be showing him this and all your responses so if you have any advice for him that would be great since it looks like he has no idea where to start "fixing" this.

I'll try and answer as fast as I can to any questions.

TLDR: Literally the title. Due to his actions I'm having him pay me for the nudes he sold and pay for any touch he wants (example: a hug). He wants to fix things and wants advice. I just wanted to vent to someone because I have no one else to tell.
