We have a date planned tomorrow night, but he hasn’t confirm plans

What should I do when me and this guy have a date planned for tomorrow night. He wanted me to pick the restaurant because I know more food places in the area. On Wednesday before we left we even said I’ll see you on Saturday. Wednesday night I sent him a text “a I’m here for you, supportive text” he hasn’t responded since, but he sees all my snapchat stories. Does this mean the plan is canceled? Please help!
