I want to continue sleeping with him but don’t know if I should

I(24f) had a long situation for a guy(21m) for about a year. We had sex all year around and I never had any issues with my body. Towards the end of the year, he got a car and everything became different. He showed me his car but would only want me to look at the exterior never let me sit or look inside.

I didn’t think about anything until one day my body felt different and I thought I had a uti. When I told him my symptoms, he was for sure thought had a uti. A week had past and symptoms got worse so I had to go to the doctor. Turns out it was gonorrhea. When I confronted him he wasnt responding and told me at the last minute he would go get tested. I was confused because he told me he wasn’t sleeping with anyone else so I got angry at him. He denied sleeping with anyone and tells me I’m the one that was with it. We go no contact. He got tested four days later and apologized. He admitted to sleeping with a girl but his story would change several times about which girl and how he got it. He apologized several times and said it’s his biggest regret.

So now months later after no contact, after the sti incident he contacted me and wants us to make up. He tells me that we weren’t really exclusive at the time so I can’t be mad at him and that he’s not a cheater. (Several times I told him I wasn’t into the hookup culture stuff no friends with benefits , fuck buddies stuff and if that’s what he wanted then leave me alone. He would always tell me that since we had sex so many times we are more than that and he doesn’t see me in that way. ) He most likely wants to have sex again and I can tell he’s still sleeping around because now he uses condoms and has a bunch of them in his car(showed me a pic). He even had them before he gave me a sti but decided not to use them with me. I really really really miss him and the sex. I doubt I’ll ever get a guy to sleep with me and if I do he won’t be as good as him. Advice.
