Did I do wrong?..

So recently on Jun 25 I met a guy on a site. He reached out to me as a friend and slowly started complimenting me. I didn't respond with anything else but with a simple "thank you". I thought he was way too attractive for me, and I didn't want to assume he liked me right off the bat and decided I'd wait until I heard it out of him. Within like the fourth day of talking he admitted to it and I started flirting back, next day he started getting sexual. I really started liking him, but he started sexting me stuff and I was kind of getting annoyed at the fact that I kept putting excuses to not send him nudes, but he kept insisting for like four days straight. Later I realized how I'd talk about literally anything non-sexual like "I have a headache" and he'd start off sexting ignoring my comment. Everything became sexual and when I finally started acting off, because I was upset, he'd say stuff like "you mean so much to me...I hope you know that". When he'd try sexting I'd say things while pissed off and he thought I was just being dirty and he basically said he'd sweet talk his way to my pants and later said it was an "in the moment" thing. He sent me a picture crying when I mentioned me not liking any of this. I literally broke off everything we had if anything, because he'd call me his, but he said before he didn't want to date just yet and rush things. So the next day he acted like if we were still a thing. I asked if he understood what that was and he said "kinda :| " so I said that was it and he kept replying with " :/ " so I left him on seen and I've not heard from him since yesterday night after that. My guy best friend said that that goes to show how much he cared, but I miss him...did I do wrong for leaving like that because he got overly sexual and just didn't really talk to me anymore? I feel like he was already trying but he also started off with trying to fix all of my "I feel sick" with a little touch here and there...
