I'm not sure it would be "in love" per say especially after such a short time, but yes its common, as others have said, check out the psychotherapy part of the forum.

its probably love like feelings though, which you can have for all type of awesome people and it is tough but you can't let it interfere, it can become promblecatic and some T's will refer you out

best advice, just tell him, he wont be weirded out, its new, common and expected.
