Relationship problems

I asked my boyfriend of a year if he saw a future with me and he said he hadn't really thought about it.... Should I be worried by that answer or did I just ask too soon? We are both still in school and long distance at the moment so he said he wants to graduate and get a job before thinking about marriage, I understand but at the same time if he doesn't see us together in his future then what are we doing? He said he just is living in the moment and taking things day by day and that he loves me and loves spending time with me and having me in his life, so am I think too much into this?
