So a few days ago, me and crush met with each other. After that day we have been chatted with each other online. He talked about things happened in his life and a few days an ago he was offline for a few days. And yesterday he sent me a snap about he watching a sports show on snapchat but he ignored my previous messages which he doesn't do before. He doesn't send me snap, we usually just chat more. Our vibes when we last time met was good. I'm a bit confused, what should I text him?
