Did I hurt him?

I met this guy at a program last week. I noticed him staring at my boobs almost in a zoned out way the first night, and I didn't think too much of it (They were fully covered by the way, I was wearing a shirt, so the only size visible). I noticed throughout the following days that he was staring at me, not my boobs. I didn't really stare back, it was more like through a passing glance that I noticed him. I didn't really know him well at this point, so I didn't care that he was staring at me.

I got to know him a little better from the way he interacted with the professors and our classmates, and I realized how he'd take my lead/imitate me for things. He would sit the same way as me, raise his hand after me, and sometimes even move to be close or next to me. At some point, some guy was trying to get me to piggyback on some other guy, and he immediately stepped in and piggybacked on the guy for me even though he wasn't willing to earlier.

The last two days of the program, he stared at me a lot less, but when we were doing activities in the dark where we were supposed to make ourselves somewhat vulnerable by sharing personal details, I noticed his eyes on me pretty much the whole time. On the last day, I remember walking by him and his friend, and I think he must have been staring at me. I remember one of his friends telling him to "ask her" (implying me), to which he responded "ask her what?" I couldn't tell what was said after that since I wasn't in earshot, but I remember that he was staring at me for pretty much the rest of the evening, till I left early.

I guess it was my insecurities that kicked in after I started liking him, and I couldn't muster the courage to talk to him. My mind would go blank when he was near.

I was able to find his snapchat account through a friend, and when I sent him a friend request, I saw "received", but he hasn't accepted it (he hasn't blocked me). I guess I was expecting him to accept it, so I'm wondering why he hasn't.

Do you think he is embarrassed and thinks I didn't like him? Is he upset with me, or maybe thinking I am using him as a time pass or attention? Is he trying not to look desperate, and might accept my request later?'

Sorry, for people who don't use snapchat, he might have not done anything with my friend request or specifically pressed "ignore request". I don't know, all I know is that he has seen it --> bc of the "received"

HE FINALLY RESPONDED ON SNAPCHAT... but he was like "Do Ik u?" which means "Do I know you?"
