If a guy leaves you on opened or read is he just not interested or did he try to play with my emotions?

I was talking to this guy from tinder 20, and he said im hot and cute but i just tried to get to know him and he left me on open. It's been a day, should i just forget it and unfriend him from Snapchat?
