Guy's Behavior

I followed a guy from my class on instagram and he followed back but later on removed me and unfollowed me , next day he was looking at my linkedin?

I just don't know what this means... we had only ever talked that one day but i thought it went really well. Also we are in college by the way. me following him was kinda me shooting my shot and i feel like him unfollowing was him rejecting, or did he remove me cause we only talked once and we aren't friends? (he doesn't have a lot of followers) also I think I'm attractive enough for him, would probs give myself like an 8/10 lol
