<human>: He's a freshman, I'm a sophomore.  We clicked pretty well at the start of the semester and we wind up spending a lot of time hanging out (dinner, homework, grocery shopping, etc). I think I ruined our platonic relationship though over a trip last week.

While I had a pretty big crush on him, I've been assuming I'm not his type (I've seen him get flirty with girls, they are typically nothing like me personality-wise) and been generally ok with it.  He keeps a pretty solid physical distance from me when we're out (not even accidental touching, he's a pretty careful guy).  

To further solidify this, we went on a weekend trip to another city the other weekend.  Initially it was supposed to be a group trip, but through some confusion it wound up just being the two of us alone in a strange city and a hotel room together. Our status quo of no-physical-contact was strictly  maintained.

I wound up falling asleep on him for several hours on the train ride back and didn't realize I was basically sleep-cuddling the entire time (pulled an all nighter before that...).  Once I woke up, he wound up changing seats to sit with a friend who got on at that stop and proceeded to say nothing else to me the rest of the evening but "goodnight".  Since then, he's said next to nothing to me and ignored the messages I've sent him.

I'm not actually sure how to go about saying I didn't mean to overstep his physical boundaries (if that's what I did, I'm assuming it is).  I rather not tell him something reassuring like "oh I'm not interested, don't worry", since that would be flat out lying.  However, I'd rather have him as a friend if he isn't romantically inclined (I'll get over in another few weeks if he isn't).  Is there anything I can do, or did I awkward up everything?

Provide a brief overview of the text.
<bot>: Been hanging out with guy, got inside his bubble on accident, now he won't talk to me.  I don't want to lie and insist I'm not interested, but I'd like to still have a friendship.
