Attract the girl by: Pursue her or ignore her?

Don't pursue her as you normally would. Give her space more than you would have before, do not answer all of her calls but get back to her a day later etc. If she asks what you are doing or why you are not paying any attention to her as you have done before, you at least have a reason. This way your safe, and it will give her time to think.

When she said she was not interested in a relationship, did you ask her why?
Given that she said she is confused about wanting a relationship, then the question to you is----can you convince her to be in one? I've met girls that have told me the same line, and because I like them, I still go out with them, and in the end we do end up 'dating.' Sometimes I think girls use that line to see how interested you really are in them. By the same token, sometimes I withdraw myself from chasing girls that tell me this, but it all has to do with the 'vibe' I get from them.sometimes I just have a bad feeling so even though I like the girl, I figure best to move to some one else.
Therefore my advice to you is, if you feel the girl is worth pursuing, then you can pretend nothing happened, and go on another 'perfect' date; if this was me of course, after the 2nd date, I would force her to ask me out.in other words, since she calls you and texts you so much, then I would say, 'instead of calling me every day, why don't you just take me out?'
Now, if you think she dissed you adn you don't feel she is worth ti anymore, avoid her texts, phone calls and find another girl that woudl be interested in you.
LIke I said, my experience has been that when girls tell you that they are not ready for a relationshp, sometimes this turned out to be a 'dare/challenge' from them to see if I was really interested, so you could have a chance, but it depends on you if you want to pursue the girl or not.
