A very confusing situation I dont know how to handle (I like really need advice about this I'm kinda worried)

hi space-hey, I'm in a bit of a pickle right now.I was talking to this guy and things were getting a little too intimate considering the relatively short amount of time we've known each other. for At first I was okay with it and even went along but now I'm feeling kind of weird.  Im fine with potentially being in a relationship online but after the initial nice warm feeling I got talking to him, lack of sleep and compliments about my looks (which no man has ever given me before) wore off I'm really starting to wonder if I might have just made some really bad decisions after he expressed feelings and asked to date me. he is from the same state but is 6 months older than me. he wants to "meet" up

in my city to "hangout" I offered to let him stay at my house for a weekend. which is when a really weird conversation started that I engaged with but am now regretting. he even wanted to (do things) I turned it down saying I wanna wait six months till were both 18 but he got odly upset at me wanting to wait despite saying I was worth it for the trip to my city and talking about consent. he also kept saying that "he wanted to $%#$* me" (despite knowing me for only three days) and all sorts of other yucky stuff which I went along with at first.which I am now really dissapointed to have said. luckily I haven't given him my address or anything (I'm not that stupid). I told him we were going too fast and that I just wanted to stay friends until then.  which would be where this typically ends and we just stay friends. but considering some of the (sensitive) things He and I Discussed. I don't know if I even want to stay friends. 

 What do y'all think. Should I just cut ties entirely and never speak to him again or should I try to continue with the friendship
