Girl you did plenty. Please do not second guess yourself. And don't worry about letting a "nice guy" go. Serial killers are nice. Literally anybody can be nice. What you want is someone who is genuinely kind, thoughtful, aware, attentive, etc. This guy was not serious. He's a talker, not a doer. Too lazy. He was trying to train you to do the work. You should not have to beg a guy to plan the date he asked you out on.
