Friends?Not friends? Are we done? What’s going on?

I will try to make it short. I moved to US for grad school some months ago. In January, I’ve met my friend’s new roommate, he’s also in my school, also moved to US recently and it turned out we were having classes together every single day for the whole semester. He just introduced himself to me and we were just chatting after every class and sometimes seeing each other because of mutual friends, being friends on Facebook but that’s it. One day he messaged me if I want to have lunch with him. After that, he was asking me for a lunch almost every single school day. We were having awesome conversations, lots of laughs and overall a great connection, something just clicked. One weekend we were on a super long walk together, then just stayed at my place cooking, drinking and just talking. But suddenly it was 2 am (we didn’t even realised) and he really had no way to come back to his place so we needed to share a bed. I just layed on one side, but he suddenly cuddled me, we kissed, have a laugh about it and both were just like “omg, the hell, it’s on”. Spend the next day together without any awkwardness, just having a good time. And it started. He was still asking me for lunch, texting me everyday, asking to hang out, we started having sleepovers. So yep, it was an early stage of dating. We decided to tell our friends that we are having a thing. And also had a really mature conversation about pacing our “relationship”. And we both agree on that this is good, we need to also be friends for each other etc. And one day suddenly he just asked for a talk. He said he’s not in a really good place mentally, because of moving to US, school, everything is out of control. He said he adores me, he totally see this working as a couple thing but he needs to step back and put his s**t together. I was hurt, but I respected his will. So I didn’t message him etc. But we are seeing each other in class every single day. I was just friendly (i’m generally a super bubbly and smiling person). Like, I’m not gonna prentend I don’t know you at all… And I noticed he’s the one waiting for me after class. So we were just chatting and that’s it. No texts, hang outs. I just gave him a birthday present and once asked if we can eat together to catch up. And one day, out of the blue, we were walking from the class, i asked about something and he started ongoing about that I’m flirting with him etc. I was shocked. I respected him, I was just being nice (he was the one waiting for me always and chatting…). He was ongoing about it, but I got super upset, just told him that I was nice and that’s it and I guess I just need to stop talking at all and just left him. Later he send me text (more like an essay…) that he cares about me, didn’t want to hurt me but I gave him vibes that I want a realtionship and right now he wants to be friends and he still blames it on his mental state and being overwhelmed.
This is a bit too much for me. Do I have a crush on him? Yes, a freaking huge one. But at the same time, I’m being realistic, I was ok with us early stage dating (lunches, hang outs, some hugs, kisses, some intimacy). We don’t know each other that long and I agree we should be friends first, because we had this great bond together. But I can’t help but feeling used by him. Those signals are so mixed. I decided on no contact rule, mostly so I can get less emotional about the stuff (it’s been 10 days now). But I miss my friend. I want to hit a “reset button” and just build from ground zero. I miss us being more intimate, but I can be just friends for now. I just don’t know how to approach this whole situation. He didn’t text me/approach me since. More than anything I miss our deep conversations, laughs, cooking together. What do I do? I still feel too emotional to reach first and I don’t know if I should. Is it still for a safe? I miss him so much.
