Background: I met this girl at a party about 6 months ago, didn't think much of it she was cute had a boyfriend kinda seemed like she was into me. Later she finds me and adds me on IG, after that basically likes every single picture of mine. I decide to try my luck and message her (by now I'm pretty sure she broke up with her bf). Also I'm moving to live on a boat with a bunch of guys for a few months so fuck me if I don't get laid beforehand.
Me: Julieeee lol hey what's up

I know it's random but I was hoping you could help settle a debate I'm having with a friend
Her: What's up
Me: Okay is kissing a stranger once cheating?
Her: Mmmm tbh no
Me: Lol and why is it not?
Her:Idk I Just feel like cheating is deeper than that

Her: I have a skewed view of relationships though tbh

Me: I get you, something like this is just something that makes for a good night
Me: And please elaborate
Her: What do you mean?
Her:Idk I just see things differently

Me: Kissing an attractive charming stranger for a night with your friends just makes for a good time, nothing more nothing less
Me: Okay I wont pry lol but they do have their good and bad
Her: That's what I think!!!
Her: And tbh I like open relationships that's why

Me: Lol you're awesome I have a whole theory about why those work best
(I realize now I could have teased her and said she was the worst person to help settle the debated based on her bias on regular relationships in general)
Her: So do I haha
Me: It's honestly more natural haha well thanks for helping me settle the debate, and thanks for the win
Her: I totally agree

no problem
Me; Lol you know what we should get coffee sometime and see who's theories are better
Her: Hahaha okay let's do it
Me: Lol awesome what day is good for you?

(btw this is all word for word)
After that she left me as seen and with no reply, honestly I thought the conversation was going pretty well, but I suppose I must have done something wrong if she just left me hanging. What do you guys think? I have a feeling I can still salvage this but idk I'm barely starting to get my feet wet in the whole world of being a pua and any feedback would be greatly appreciated.
