Ok, theres actually a lot more to the story, but here it is in a nutshell. I meet a HB7 at a party and we start talking. I'm still really AFC, but i'm doing my best at keeping the conversation going and is seemed to be working. Anyways, after a while she starts giving me some IOI's and after like 20 minutes she asks me for my e-mail (which was not as weird as it sounds, i didn't have my phone at the time). I didn't have a pen or paper on me, but she said she did in her purse which was back in her car.

Anyways, i was just wondering if that was an invitation to go with her to her car, or if i'm just over thinking it? This has been bugging me for a few days now...

relax, if it was and if it was not don't really matter no more, just keep it moving with the next convo and get that phone number lol

Theres no way of knowing, but you can always offer to walk her to her car.
her: "I have paper and pen in my car"
you: "Thats great I'll walk you to it."

Sounds like an invite to me.

Next time offer to walk her to her car like kodierer said.

Why does it matter if it was or was not an invite? It doesn't as far as the sarge goes. If you're just wanting to learn what you could have done better than here it is:

Whether or not she was consciously inviting you out to her car, she gave you an opportunity that you missed (It's no big deal, this is just constructive criticism). Instead of offering to walk her to her car, I would have suggested the following:

Her: "I have paper and pen in my car"
You: "Awesome. Let's go! (Give her your arm, so you can escort her) That's all you get - don't get any ideas. By the way...blah blah."

Once you get to the car, you have successfully isolated your target. Perfect! Continue with your routines, establish some comfort, and turn that email-close into a kiss-close!
