Screwed up text convo with girl - constructive criticism welcome.

Number closed girl off badoo, transitioned on to whatsapp. At this point, everything was going ok, just regular chat.

Her: Hey you, (name) here.
Me: Welcome. So many weirdos on badoo, hope you're not one of them
Her: I think I am not one of them, maybe sometimes a little bit weird but not like that way (starts qualifying)
Me: Haha tru, whats doing tomorrow
Her: No plans
Me: Lets meet up 2-3 pm
Her: Yes I think that is ok
Me: K cool, I will just hit u up tomorro
Her: thats okay
Me: Where bouts in the city u stayin (sussin' logistics)
Her: In the city  (name of hostel)
Me: ok cool, a lot of travellers in ur room ?
Her: No twin room, better than sleeping with 10 people
Me: "*laughing emojii**, then i ask her for a pic, since i am not clear on wtf she looks like, so she sends one, i send a thumbs up
Her: **smiler face**
Me: So, i am thinking we just chill out, grab some ice-cream or some shit like that. Lemme know since I am in the city now.
Me: sends some stupid ass dude chasing a balloon using emojois (duno why)
Me: Im in city now, meet you in 15 (tryna make things happen now)

No reply.

I fucked it up. 1. Shouldnt have given her the opportunity to say "Lemme Know". thats a major fuck up. 2. Shouldnt have used the word "shit", just makes me look incongruent, since before everything was simple. Shes 19, and is coming across very shy and straight-forward.

Any way to re-engage, any extra tips and mindsets to have so this shit doesnt happen again. Fuck it feels so gay.
