I met this girl at a Halloween house party. At the end of the night, she told me she was leaving and making moves to gather her stuff, and I asked her if she and her friend wanted to come back with and my friend. She said she had to go to her home town (with her AFC guy friend that she came with). Stupidly, I just said "OK!" when I'm pretty sure I could have easily closed the deal, because after I asked her if she wanted to come back she basically dropped her guard and started talking to me again like she was in no rush to leave. I still assumed she needed to get home - I wasn't educated enough to realize that all girls give a "no" the first time (but now I know).
Anyways, I got her number and here's the text. I'm wondering if you guys can help me with what to say next, because I may need to build up the attraction again:
Me: OMG! You are not going to believe what happened to me last night! [10/29 4:51P]
HB: Got a new phone who is this [10/29 4:51PM]
Me: Oh sorry wrong Becky [10/29 4:52PM]
HB: Wait but who is this [10/29 4:53PM]
Me: Dr. Bush from Jake's [10/29 4:54PM]
HB: Ohhh got cha [10/29 4:55PM]
Me: Hey you have any plans for tonight? [11/2 1:40PM]
HB: You texting the right Becky this time [11/2 1:53PM]
Me: Lol yeah [11/2 1:55PM]
HB: Oh good good... But I might have plans I'm still unsure why what's up [11/2 2:17PM]
Me: I'm having a few friends over and then going out in (My Town) or (Next town over). Was curious if you'd like to join the fun [11/2 3:04PM]
HB: Hmm tempting I'm still debating I'd I wanna go out cause I gotta work at 730am tomorrow [11/2 5:16PM]
HB: But I'd I decide to go out ill let ya know for sure [11/2 5:16PM]
Me: Best i can promise is a good time. For everything else you're own your own

[11/2 6:11PM]
HB: Haha I'm actually gunna pass tonight I got an early day tomorrow thanks for the invite though hope you have a great night though [11/2 9:08PM]
So my only comments are I should have probably said something like "That's OK I have to get up early too" instead of "best I can promise is a good time".
Any thoughts on this convo, and what I should text her next time? Should I just invite her up same day again Saturday? I haven't messaged her since, and didn't say anything after her last reply.
