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

Even though you got confused, I'd say your last message was good: you've set a date frame in the context of the conversation. Just re-engage her in some time.

You've gamed to much instead of carrying a normal conversation and it came out creepy. She asked why you've added her, I'd say something like "I though you were cute" and then shoot usual shit. Remember that Snapchat has got different dynamics than Tinder (probably more similar to Instagram), check out Alex's video on Instagram, he explains it in a smart way.

I'm sure it would've been better if you've kept that sex talk going. You started it well and then you haven't pushed it further, I'm sure that she wanted and expected that.

The best response would to have a conversation with her lol :D

That could be the case. Thanks man

She had shown you interest, reward her by showing yours.

If you like her and she's into you, why not? I wouldn't stick to the 1st one unless you're short on options.

I'd say you won't go anywhere with her, she flaked you and then she said she's not looking for anything. Stick with her cousin ;)

Any experience with Swiss or just in general? I've spoken to some people who have been there and I've heard that dating in Swiss is atrocious, because people rely on heavily on social circles and are not open to strangers.
