I think he thinks I'm weird?

I added this guy who I thought was in my orientation for college and turns out he wasn't so we tlaked etc etc. he said "no worries :)" TWICE and I did comment a pic of him playing a sport and he asked if i was in a sport in hs and i was like yeah tennis and he's lke "that's cool :)". Dang I hate when people say short answers and put smiley faces like that makes it better. Ugh he obviously wants me to stop talking to him considering I totally mixed him up w/ another guy. ALthough this guy is pretty cute too, I'd be open to talking to him, he's not interested in talking right?
