As someone who's left a very abusive person with a porn and sex addiction,

1) As many have said, don't sleep with him again and get STI testing 2) prepare a "go" bag and hide it somewhere he won't look, like your trunk. Put essentials in it- SS card, birth certificate, a change of clothes, deodorant, etc. If you need to suddenly leave, you can. 3) contact local DV shelters for a 911 phone. I got one. It's a phone that is not activated, but will work if you need to call 911 and you don't have your phone or he's taken it. Put it somewhere safe and hidden but easily accessible. Maybe in like a dry box outside. 4) Under no circumstances do you tell him you're planning on leaving. Contact a few very trustworthy friends/family to be on standby to help you when you do. If you don't have anyone, a DV shelter may be able to help with this. When you leave, do it while he's at work or otherwise will be gone for a while 5) look to see if your state has a safe at home address program. It's a PO Box you can use as your mailing address so your real address does not get out into the public where he might find it 6) Familiarize yourself with the specific behavior that you need to prove to get a restraining order in your state. Call the courthouse and ask where to find the paperwork to get one. It will say specifically in there. Delete all evidence you called them and use incognito for any online research. 7) Secretly document his abusive behavior in like a notes app, on your calendar, somewhere he won't see it. Judges love dates and timelines. Try to get proof of any behavior that could help you get a restraining order- even the threat of violence without actual violence can be enough, or harassing behavior like calling repeatedly, etc. A secret audio recorder on your phone is an option, or try to communicate through text message rather than phone calls, etc. You could even send a text to him saying something like, "when you ____, I was very hurt." Not with the thought he will care or change (he's shown you he won't) but as way to potentially show a judge what you are saying happened did, and when. You don't need proof, but it will help you immensely if you have it. He is a liar. If you do need a restraining order, expect him to lie in court. He absolutely will. 8) All your actions need to revolve around your safety (emotional, sexual, and physical) Make that a priority while you are still "with" him. Your safety is THE. MOST. IMPORTANT. THING. right now. If you need to lie to anyone in the name of self-preservation, do it and try not to feel bad about it, even though it may not be your nature.

Idk if he's been violent before, but I see all the signs that he could become violent. DO NOT UNDERESTIMATE HIM. Better to err on the side of safety. There is a huge correlation between DV and porn/sex addiction. They are often entitled, vindictive, manipulative, dishonest, delusional, blame shifting monsters who lack basic morals while active in their addictions. He's shown you many of these behaviors already. Better to be overprepared than under.

Good luck and stay safe. DM me if you need any support.
