19 year old girl - meetup - boring convo?

Met this 19 year old girl in a bar. Stole her from some dude and grabbed her number. Her friends was trying to drag her away several times but she stayed put with me.

Me: Get home safe. Lotion
Her: You too :)
Me: Hey *name* I want to see you again. Up for grabbing ice cream next week?
Her: Okay sure, what day do you have in mind?
Me: I'm pretty free the whole week. u? :)
Her: Wednesday is best. Since I'm working mon,tues and thursday.
Me: Wednesday around 4:30 then. ur not a flaky person are u?
Her: Sounds good. Uuhm, I'm a little bit I guess. why?
Me: Lol cause if u flake on me, I'll have to send u the divorce papers dear (Felt this was unnecessary overgaming.. feels so gay..)
Her: Riight.. Well I'm at the cinema with a friend, so talk to u later


Anyways felt it was pretty straight forward getting the meet. But I felt like there was missing that emotional spike in the convo that would've cemented the meet more.. or am I just overthinking here?

Then I went a bit too gay at the end..

Thoughts?
