He just stopped texting, but he still follows me on instagram and snap chat why?

So I was talking/seeing this guy I met online for a month. He was initiating majority of the contact either through a text message or snap chat in the morning and conversation would continue off/on throughout the day. He also added me on instagram and snap chat.
About a week ago the communication faded out and I haven’t heard from him in a week, but he will still look at my snap chat stories that everyone can see. To top it all off he told me the day after meeting me in person that it was rare for him to like a girl as fast as he did me so I must be something special. Following that statement he said he hoped this could turn into something. We would hangout at least once a week and sometimes more if I would stop into his clothing store to chat for little while with him. He even invited me to event he hosted at his store which was weekend before the contact stopped. His friends asked me to join them out and I was hesitant because I could tell he was stressed, but he never once told me to leave. The next day he even sent me text apologizing for acting like a jerk and said him being irritated and stressed was no excuse for it. I have attempted to reach out to him via text message couple times asking if something happened or if he was seeing someone else, but have received no response. I can only assume he’s seen my texts since he’s looked at my snap chat stories since his lack of communication. I’m at a loss right now because I felt like things were moving along naturally and at good pace. He showed and verbalized interest. Guess I’m not sure what more I can do at this point?
