My crush opened my snap but didn’t reply?

Ok, so basically I have been talking to this really cute guy and we have been msging for a few days. Used to know him and we just got back in touch. Anyway yesterday we were having a good conversation and he was being kinda flirty too. But today I msged him hey, he replied hey but when I asked him hru he opened it but didn’t respond. Has he lost interest in me? What do I do?
