I know this is a long read but bear with me!
I met this HB8 at a friends party last saturday and after the party a few of us went to a club and I kiss closed and got her number.
Two days later I sent her a text and we were sending messages back and forth pretty much all day. I tried to use open loop questions to create a bit of intrigue as well as throwing in some innuendos here and there to keep some sexual tension. Very early on in the text she said she wasn't feeling so good in her stomach, hadn't been able to eat much at all etc. and she was talking about being stressed because she was starting a new job next week and I basicly said this:
Me: "I guess you just need to do something fun to get your mind off it

" (I guess she thought I meant sex, which I didn't lol, was just going to ask her out)
HB: "hehe yeah probably, dont know if that would work:P I tend to overthink things tooo much :/:P" (to me it sounds like she's talking about sex)
Me: "I understand

I just like to get out of the house and meet friends and have fun to get my mind off of things" (I acted like I didn't realize she thought I meant sex)
HB: "hehe yeah thats actually true

"
Me: "I've got a crazy idea but I don't know if you're adventurous enough for it and no I'm not talking about sex [name], you've gotta get your head out of the gutter!

just something fun to get your mind off of things

"
HB: "Hahaha so funny:P"
Me: "Haha

Have you tried 7D cinema?"
HB: "Haha yeaah its awesome! I screamed so loud when I went the last time, just like being on a rollercoaster haha

"
HB: "just a little bit hehe"
Me: "haha yeah it's really awesome! I'd really like to try it again

it's so realistic, are you free tomorrow?

"
HB: "Umm yeah maybe, if my stomach feels any better :/:P I actually saw both the movies, I just had to see the other one when I was done with the first one hehe"
It didn't sound like she was super excited about going with me and made it sound like she's seen both the available movies and thus didn't have to go again or something like that so I just ignored the fact that she said she wasn't sure and kept talking. For those of you who don't know 7D cinema is like a movie in 3D where you sit in a chair that moves with the movie and air blowing in your face and it's also like a computer game because you have a gun and you need to shoot bad guys on the screen or something like that but each movie is just like 5 minutes long so it's just something fun to do and not at all like a regular movie, so it should be something you could do again and again even though you've seen both the available movies.
This conversation occurred two days ago, I talked to her a little yesterday but she said she still had a pretty bad stomach ache and she was actually the one that sent the last text to me but I decided to freeze her out a bit and haven't heard from her today. But I was thinking about sending her a text tomorrow along the lines of "something made me think of you" or something like that and then from there try to set up a date.
She's leaving town sometime on june 5th-8th for her new job (she's not exactly sure when) so I'm wondering how I should approach this, when do you think I should send another text and ask her out? Should I rather call her? Should I suggest another activity for us to do together? I thought the 7D cinema thing was a good idea because it's fun and it's just like 5 minutes and it's at the mall so we could go window shopping afterwards and get an ice cream or something...
I'd appreciate the help guys!
