Guy troubles? I appreciate any help from the Y!A community :)?

Hmm, I don' t think its really anything serious because from what you say, this guy is really into you. The best answer I could give you is to casually bring it up in a conversation and ask him who the girl is, without freaking him out that you've been doing a little bit of research on him(which i can relate to because i would do the same if i really liked someone) . It probably might turn out to be a friend or his cousin. You never know till you ask!
