Confused

Okay so I’m 16 and the guy I was talking to is 17 and I’m telling you our ages so I think it plays a big role. Okay so anyway me and this guy established that we were talking cuz he asked me if I wanted to and I said yes. And me and him have only been hanging out for a week and a half. Anyway he was super fucking sweet and inviting me to church and meeting his mom and to meet his friends and brings me around all of them. So I was like yes he’s not hiding me and he’s being serious! And he’d tell me all the time that I’m different and I’m a keeper and he wanted to see me all the time. And asked me out on a date. And it seemed soo perfect ! So last night he got to my friends house and he asked me to go downstairs w him and I was like okay cuz I’m gullible and shit. And so he starts going at it and trying to have sex. And I was like no and he was trying to finger me and I told him I was on my period and he kept trying. Then he asked me to suck his dick and I said no cuz that’s too fast. And so then I told him that my friend texted me and wants me to come upstairs when she rlly didn’t. And then we start going upstairs and then he picks me up and throws me back into the couch and tries to do more shit. And then we finally go upstairs. And he smokes weed and acts soooo weird and he got way to high. And then he ended up leaving w his friend and he didn’t even hug me bye or anything and I was thinking it was cuz he was high. And the next morning he didn’t tell me good morning or anything but I did play him back in cup pong . And he was like I’m sorry about last night. And he didn’t say which part. But then last night he tells me that we should just be friends for now and get to know each other better. And I said I was thinking the same thing but we should stay friends. And he says why? And I said why do you wanna be friends now? And he said I’ll talk to you about it later tonight and then he never told me. But tbh I was feeling different about him too from last night. But now I’m sad cuz after we did stuff now he wants to be friends. I wonder if I did something wrong ?? Idk I need opinions ASAP! Like i wonder if it’s something else but idk I hate this
