"I prefer to see how the chemistry is in person instead of over online chit chat, which can get boring, and we matched so lets keep the idea of a date in mind"

lmao is idfk u mean I don't fucking know you? Bro do you even know this girl

I assume you don't know her and you're talking about a date out of nowhere. Snapchat is different from Tinder, there's no social agreement that talking to each other means something romantic. Check out this video from Alex: https://www.youtube.com/watch?v=yLjijGHj1-I

I think you were being kind of whiny about her slow response. Like at least if you're fun about it, such as posting the skeleton meme, etc - it can be OK. but you were just whiny. And then you want her to "make it up" for being slow to respond? The reason she's responding slow is she has low interest in you and now when you go harsh with her of course she tells you to take a hike.

just give me a heads up on what I should know about you. See if the vibe is right.

dude idk she doesn't really know you it sounds like but shot in the dark.

Missing context, how did you come to be talking on snapchat? It makes a difference
