Am I in a relationship or not?! Guy confusion?!?

I would say you are "dating" each other. If you want more, or are confused, next time you see him in person, ask him if he would like to be your boyfriend, or if he'd like to be exclusive. Usually if it's not stated as being exclusive, it's not. Just be prepared, that if he didn't want commitment, he might not talk to you again. If you do want more, and that happens, good riddence. If not, good for you! :)
