Need advice

Ok so ive been talking to this guy just for a couple of weeks. Everything seemed to be going well, besides the fact that we are in two different states. We had really good conversation getting to know each other that just flowed naturally. It was going well then one day just went dry randomly its been a week since we texted and he’s been liking my instagram stories but hitting me up. I really wanna just ask if he’s in a relationship or something because thats the only thing that makes sense in my head, since everything was going REALLY well.
