Match disappeared, need advice!

Hi all, would appreciate some advice on my situation. I (31f) matched with someone (31m) last weekend and it all seemed to go well when chatting. We made arrangements to meet up at a cafe this Saturday which i was keen on as i thought we got on well. I replied to his last message yesterday evening and didnt get any notifications of a reply after that. I checked the app earlier to ask how he was going and the match has disappeared. I dont know if the unmatch was on purpose or accidental.. Should i show up at the cafe at the time he suggested or should I let this go?
