Does ignoring a woman make her more interested?

She may be interested, in your company, and the attention you give her.

She doesn`t want to give you a straight answer because she doesn`t want to lose you (the attention).
You are her safety net. When she has nothing else to do (bored), or when she needs self reassurance, she talks to you. She would probably call you, but she knows you would do that for her, so...
If you ignore her, ofcourse she is going to think about you. --Wonder what you are doing, and why you`re not chasing her anymore. --But it doesn`t mean she will like you any more than she does now.
If you tell a girl how you feel, and she doesn`t respond to it, EVER, then it means she doesn`t feel the same. Even if she is not the type to express her feelings verbally, her actions would at least tell you something. In this case, her actions tell you she is not taking you seriously.
If you continue to pursue this girl, I think you will end up heartbroken. I suggest you start moving on. If she REALLY likes you, she knows what she has to do. But I, personally, wouldn`t wait on it.
Don`t get fooled when she texts you out of the blue... it is mainly because she is lonely, looking for someone to talk to, bored, or some other dude dumped her/made her feel bad.

If I`m wrong and this is her way of "playing hard to get"... then your relationship with her will be full of mind games, now and in the future... do you really want that? I think you can do better.

I'm not a fan of game-playing. If she's not calling you back, I'd consider talking to her about it directly. As for ignoring her... if I guy did that to me, I'd be most likely to assume he isn't into me and I'd move on.

To answer your question, I think it has more to do with the individual woman's preference. Me personally, I hate it when a guy acts aloof an distance without warning; makes me wonder if I did something wrong and gets me feeling a bit insecure.

I think it's best if you do a mix of being unavailable nd showing interest in her.
In general, we all want what is unattainable.
If you show too much interest, that means ur too available.. nd that's not attractive
But then again, if you act like you don't want her too much, she'll move on .
So do a mix of the two and you should be perfect :)

Sometimes it's a nice little trump card to play. But if overused, a girl will most likely move on. Give her a lot of attention at first, and if this still doesn't make her more interested in you, then drop it. If she starts to wonder why your not doing any more advances, it's safe to say you have her interest right then and there.

It may work with some girls and have a bad reffect with others.

"I would call her, Then she will tell me she will call me back. She never does."
Instead of accepting "Ill call you", just fix a place and time, or better, an hour you'll pick her up at a place she's bound to be, home or school and be there. It may not work but it's worth trying.
