Date with a bumble guy

So I went on a date with a guy I met on bumble . He was super nice and mature and the conversation flowed naturally. We had some drinks and then went on a walk . We had an amazing time and we both didn't want the night to end . This guy was only in town for the night but lived a few hours away . We snap chatted each other after that date for 2 days . All of a sudden he isn't talking or answering my snaps but he is opening them . Should I be worried he isn't interested anymore or what ?
