Sorry, I don't speak guy, can someone translate?

I have been 'involved' with this guy more than a month. We talked and messaged each other for a couple of weeks going on our first date. We go on a date at least once every week. We live 45 minutes apart so its harder to see each other everyday. But we message each other everyday (at least 50 or a day). We also talk on the phone every day (usually for 2 hours at a time). My question is this, when I asked him where we stand he said we are more than casually dating but not going steedy. What does that mean?
