<human>: So I (22F) have a friend (24M) (if I can actually call him that) who I assumed I was getting along with. My normal mode of operation is to assume platonicity unless I get a super overt signal, because it would be a bit self absorbed to think every guy I know is interested (and also untrue). So little by little I feel the signs of a budding friendship as we would hang and chat more and more about lots of things; personal, academic etc. I'm also fairly oblivious when it comes to signs that may point to other things. Anyhow, to get to the point, there was a short period of him trying to get us to do things together without necessarily involving a group as we normally do. I personally didn't think anything special of it except: yay! new friend! While I definitely wouldn't mind starting anything, it wasn't really my main thought. I'm not entirely sure if my behaviors were portraying this thought, as I started to do the same things, asking about eating to together, hanging out, etc. 

Fast forward a few days and I'm getting the cold shoulder. Like avoiding eye contact and running away from my presence, even if I'm across the room talking to someone else. If we are within even peripheral vision of each other, he runs away. Because this isn't something that has had much history, I'm okay with just letting it fall, though he was one of the few people I could talk to about certain things. Why do people do this? Should I ask to make sure everything with him is okay or just leave it alone?

Give me a shortened version of the text
<bot>: Cold shoulder from friend(?) randomly after becoming slightly more intimate (not on a physical level). Should I ask what's up or just forget the whole thing?
