How do you guys deal with women that a hard to draw emotion out of.

For example I ask this girl out for a drink ending with a joke about her when she played a little joke on me when she was drunk (only time she has been funny). She replies with a yes to coming out but nothing else. No game what so ever.

Previously i had said something like 'great night, your nearly as cute as me', to which she replied 'thanks for dinner'

She has been up for meeting a couple of times and never let me down but the lack of emotion and gameplay from her knocks my confidence a bit when I am with her. She also seems nervous around me sometimes.

How can a break the mould, or maybe she doesnt like me?

Girls like this deplete my soul, I swear one thing I've realised lately is I'm more attracted to girls with average looks and great, vibrant personalities than hotties with dreadful personalities.

Maybe try teasing her a bit? "Wow you're like a robot, do you come with a manual that tells me how to turn your sense of humour on :p" that type of thing? That will only work if she's secure enough to take it though.
