Just ignore who? (I'm too lazy to look up the other posts)
From what can be gathered here almost sounds like one-itis, in any case though you can't lose anything from ignoring a girl who plays games, isn't working for you, just wants to be "friends",etc. Get on with life and ignore her not to try and hope it'll make her want you more (although that's very well possible) but rather becuase you are so occoupied with other women that you forgot about the original woman! Then after you get a taste of what's out there (it's the mindset that this is the only woman available to you and you HAVE to have her or else you may not get anyone else that is the problem) you just may think back 'what the hell was I thinking with this one anyway?'
Being unavailable (ignoring her) is much more effective than being too available and being taken advantage of.
