Ah, my area of expertise. To answer this question, we'll need to venture down into the stygian depths of the female psyche. When it comes to attraction, girls are herd animals. They're attracted to guys that other girls are attracted to, and partially because other girls are attracted to them. Point is, an attractive guy is a guy with options. The corollary is also true: a guy with options is an attractive guy.

Which brings us to the salient point. How does a guy with options behave? And the answer is obvious: because he has options, he doesn't need to invest too much in any one girl. He can find a replacement without too much difficulty. So he can afford to ignore her or tease her or send one-word answers to her texts. Whether or not he actually does have options, at the subconscious level that sort of behaviour will make the girl assume that he does. Meanwhile, her assumption that she's easily replaceable will make her try especially hard to keep him around. When you say you want to see him and talk to him more after he ignores your texts, that's why.

But here's the thing: he probably isn't doing this deliberately, or even consciously. I mean, maybe he'd spend a week or so texting you more often, but I doubt you'd see any kind of long-term change in his behaviour from talking to him about this. And really, it sounds like the only thing you're worried about is getting resentful in the future. If you're aware that that's a possibility, it's already unlikely to happen.
