Give it time. Girls generally don't initiate right away unless you build a hell of a lot of attraction. Which I'm assuming you didn't, because you're here posting on why she hasn't initiated anything. Keep talking to her, flirting/attraction building, and she'll eventually come around.
Text her. If you hung out with her you should get a kind of feel for what type of girl she is. If she's a little more coy she most likely is going to want you to take the upper hand.
One thing I've learned from a buddy who is a solid natural is that shy girls are usually just as bad as the bad girls, they're just waiting for you to allow them to feel comfortable around you. He's an extreme narcissist and loves to talk about himself, but keeps it interesting. Try asking some questions and then relaying them back to you in a fun way. As you open up, she'll feel more comfortable around you.
Met at a bar, she was with her friend. Her friend wanted to go home so she ditched her friend to be with me. We didn't go all the way because she did not really want too but was still fun, talked a lot and found out we have quite a bit in common. She takes a few good hours to text back which is annoying and I know shes doing it on purpose ... i ended up asking her out and she said shes got work on x day but will let me know later on.... unsure if shes playing hard to get or not interested or has others on the side
I see. Those are logistics that you can't know and shouldn't worry about at this stage. I tend to like to give girls the benefit of the doubt because life happens. There have been many cases for me when a girl has flaked, and I overreacted and found out that "life" happened, and that the girl liked me. Just give it like 2-3 days from the day she didn't text you and reopen her. Depending on how that conversation goes that'll determine if you ask her out then or if you need to give it one more exchange. If you think she's taking a long time to respond to your text, it could possibly be a sign of disinterest, but honestly don't give a fuck. Be fun and flirty, and push for another date. If it happens it happens, if it doesn't just move on. Never just focus on one girl to begin with anyway.
It sounds like you built attraction with her at the bar, and nicely enough got to hook up a little, but she never fully felt comfortable. Typically it's 2 steps forward, one step back, but you may have to take a couple steps back here. Give her a little reason to remember why she became attracted to you and then work on making her feel comfortable, Fluff if you will. Then you can work up to asking her out. It could take a little time and some solid text game.
