Been gaming this girl, she has shown the following IOIs (at least I think they are IOIs):

Texts and FB chats a lot. She initiates 90% of the times. Always says something when we are both online, even though I've just been with her.
Stands/sits next to me when we are in a group setting. I am also the person to whom she speaks the most, and sometimes fights other people for my attention when I am talking to someone else.
Walks real close to me. I have used the oportunity more than once to brush hands with her (like Gambler teaches) and she never backed down on contact.
Was receptive to some kino. Lower back, waist, legs and face touching, kiss on the cheek (no chance of closing) and somewhat reciprocated. Was also receptive to me "forcing her", like putting my arm on her shoulders and guiding her away from a clothes store at the mall or pulling her by an arm when she takes too damn long and the rest of the crew is waiting.
Gave me excuses to touch her (said she was cold and i put my arm on her shoulders, said her hands were cold and did not flinch when I held her hand, asked for my arm arguing the floor was slippery).

BUT, and there is always a "but" when you are chasing some butt

Flaked on a 1 on 1... twice. One may have been a valid schedule conflict, the other time she asked a mutual friend to come along and flaked because she was unavailable.
Mentioned an ex-boyfriend and the good looks of some steroid freak reality show contestant.

I am also the guy she called when she had a fight with her best friend, wich is a clear indicator of being in the friendzone.

I pondered the posibility that she is shy and intimidated by me, and there may be a chance I overgamed. But she frequently talks about sex, and is kinda known as the group pervert. Reminds me of Delinda DeLine, from the TV show Las Vegas. You get the type, not shy at all. That also means building up sexual tension is not an option. Just keeping up with her is like poker night at the local Hell's Angels chapter.

Is she interested? How do I pursue?

It's immaterial whether or not you're getting an IOI. What matters more is that you believe it is.

What do you think will increase your odds in scoring a woman, BEING that confident individual believing you're capable and deserving of the good things in life, or the guy who feels cursed, that no matter what he does he's destined for failure.

If you believe its an IOI your confidence in 'winning' someone over will likely increase dramatically and more often then not you'll benefit. If you are continually questioning whether she's giving you an IOI or not what will happen is that any IOIs she's truly giving off you'll downplay (negative self-dialogue).

Worst case scenario and she wasn't giving you an IOI all is not lost. She still may like you, or even learn to like you. And if not, no sweat off your back, there are plenty other women out there who'll be receptive to your advances.

Thank you.

So basically I run my own game and where it leads...
