Isn't over his ex but seems somewhat into me (mostly a rant)

I met this guy about a year and a half at uni. We pretty much instantly got along and we super great friends for first term. We had a bunch of mutual friends that would tease us about being a couple or being cute together. The next term I had a bit of a break down (unrelated to any of this) and went on the wrong meds and things got real bad. He was there for me through all of it and was massively supportive. He also started a secret friends with benefits thing with a mutual friend, who previously had been making comments about and he and I were cute together, it was weird. Anyway he put up with me being overly emotionally dependant on him for 10 weeks and then I dropped out to go home and get my self together.
Fast forward to earlier this year, he randomly gets back in touch with me, we had stopped talking as much, and we started texting again. I end up booking flights to go visit him and our mutual friends in a few more months time. Anyway my trip comes around and I stay at his flat with a bunch of our friends. I end up sleeping on a couch which is too short for me and the cat keeps jumping on me during the night. I do not cope well with sleep deprivation so on the 3rd day he’s like hey if you want you can sleep in my bed and I’ll take the couch for a night. A bunch of us go out that night. I am an idiot so I down to glasses of wine and throw up, and he is super nice about it and just chills with me till I’m feeling better and I’m like boy, I am gross. Anyway we get back to the flat at like midnight and I’m exhausted and still feeling super ashamed about the wine incident and just want to sleep in a bed so I take him up on his offer. He’s like yeah that’s chill and so I do my teeth and claim his bed. Then he asked if he can ‘use the other half’ and I feel super safe around this guy and was like sure whatever I don’t really care. He then proceeds to get into the bed and immediately wraps his arms around me; the only other times he’s initiated physical contact is pity hugs when I’m crying. We end up cuddling, and talking for hours, including about how he regrets breaking up with his ex who he broke up with at the end of high school, but then his behaviour isn’t entirely platonic. The next morning we end up lying in bed awake with his face buried in my neck as a run my fingers through his hair for an hour and it’s just really nice and sweet. That day we act as if nothing really happened and that night I ask him what’s going on in his brain cause I know we’re still just friend but its all very weird. He says he isn’t sure how he feels, ‘wouldn’t want to do long distance with you’ and says sorry for sending mixed signals, and apologises heaps. After a few more days I go back home and since then we’ve been texting pretty much every day. This guy tells me really personally things and I will ask incredibly nosey questions but tell him he doesn’t have to answer, but he genuinely tries to answer and explain him self to me. We’re best friend but I want something more but I don’t know if he’s really confused or doesn’t want to hurt me and it’s just really difficult not have a clear answer about whether or not something could happen between us. I hate uncertainty. Also I should note that as I my anxiety is now managed and I’m so much healthier than I’ve really ever been, I’m planning on going back to that Uni again next year because I love the city it’s in and have a bunch of friends down there and have a support network and know my way around (or at least that’s what I tell myself). I also know what things to look out for in terms of me getting bad again and I can always come home if it’s still too much. Anyway we’ll be in the same city so he’ll theoretically have to sort out his feeling but he often seems to supress things so I’m not sure he will. Anyway boy’s are stupid and I’m even stupider for liking one. If you have any advice please help
