So the backstory:

There's a girl I met, some time ago...at this point it's probally a year. To sum it up, I met her, did all the right things, took over the situation and dismissed some AFC's who were around when we met, had a great conversation, hit it off, confidently got her number and attempted to start some text game. I noticed immediately that her responses were few and far between, and very vague. I think I gave it 3-5 days of trying to start a worthwhile conversation. The delay in responses was usually hours, sometimes a whole day. I made the decision that there was not enough interest (vs. thinking she might be playing hard to get), I ceased conversation and moved on.

Fast forward, a few months went by and what do you know, she starts texting me (what are you doing, what's going on tonight, etc etc. playful flirty conversation) So needless to say, My interest was slightly rejeuvinated. This is a girl I see semi-reguarly by the way, who works at a place I sometimes frequent. She invites me to a company party, I take this as wanting to hang out with me. To sum it up, it didn't go the way I planned. The night went great, converation was 1 on 1 and good, no lull's or akward silence, but later on in the evening I overheard her talking to a friend about another guy and possibly him picking her up and taking her home. I politely got up, without showing emotion or anything and left. I wasn't jealous, I just remember thinking, she's a bit flighty and playing her different options, I'm going to take one of those off the table and walk away.

Current: Why do I mention all this? This is a girl I actually do like, who is extremely attractive with a great personality. For months on end, on and off there's been flirtation met with apparent non-interest, then what appears to be interest/texting, which results in getting blown off. I know people are going to say, "dude you need to move on." Don't be mis-guided, I have moved on...met and slept with a good handful of girls throughout this course of time, however this is ONE girl who if I could re-spark some interest, I wouldn't mind getting with.

I guess this is a sticking point for me because when I see her, she greets me with a long, squeezing hug (but only me, never anyone Im with) is always walking by hitting me on the arm, playful hitting, always seems to end up close/next to me, smiles and laughs with me, teases me (in a playful way about clothes and such, personality traits) almost all signs when In person, point to attraction, but when I try to break through and take it a step further, I'm left second guessing all of that. She is honestly one of the hardest girls I've ever encountered to figure out. I've only kept her in the back of my mind, and remotely on my radar, because I feel she is a good learning experience, and seemingly very complicated to understand and conquer, it's a challenge, I like that and at this point my time and energy invested in it is minimal, but when I see any type of window, I usually give it a shot because she'd DEFINATELY be worth it if I were able to escalate things. Has anyone, who considers themselves a very smart and intuitive person, easily able to read people, ever come accross a woman/girl such as this where try as you might, the signals are so mixed you find yourself simply saying WTF????

I'm sure some people will suggest a more direct approach to determine her level of attraction or interest, such as light touching or methods via conversation leaning towards more sexual ideas, but I just havent been able to get enough of a green light to go there, she's like a brick wall...albeit...a good one to learn from.
