||...when I see something this bad, if it's someone violating our anti-trolling rule. But let's at least seem to take this seriously for a moment, and consider the issues raised.
I introduced my self to her, and it went really well. Not wanting to inflate her head too much, I ignored her for a week.
Translation into English: You started playing head games on day one. Bad way to try to start a relationship. Indicative of an asshole.
She seemed hurt by it, so I apologized. [...] I saw her a few days later, [...] and told her I was confused.
What did you have to be confused about? You were a jerk to her and she wasn't impressed. Why is this a surprise?
Today, waiting for class to start, I overheard her and the said friend actually laughing about me feeling bad about this.
You don't tell us what they were actually saying, so this is hard to decipher. Maybe they were just laughing about you being such a jerk and thinking that you were going to get somewhere with her by being an asshole and then putting on a sniveling pity act. Which is sort of amusing.
I now understand
why men are to treat women like shit - they crave it.
There are some women who seem to need to be mistreated, but that's usually because they were raised in abusive homes; they subconsciously expect to be hurt, and they think that's what people who love you do to you. ("If he didn't care about me, he wouldn't bother hitting me.") Unless you're stupid, you don't want to be involved with that sort of woman, because she'll make sure you suffer as much as she does. Fortunately, that sort of woman is a minority of the adult female population.
Additionally, some very young women (and from your tone and your references to school, I'll guess that you're still in your teens, probably still in high school, or maybe even middle school) go through a period in adolescence in which, having realized that their sexuality gives them some power over men (or, more accurately, men give them power because of sexuality), they experiment with manipulation and minor emotional cruelties. Most of them outgrow it after a few years. (This is one reason I'm glad to no longer be a teenager.) So don't make assumptions about the nature of women on the basis of a few teenage girls on a power trip.
Lastly, and perhaps most relevantly to your case, like tends to attract like. Reading your story, I don't see the slightest trace of anything in your nature that would make you a good boyfriend. You're obviously self-obsessed, you play stupid head games, and you're an immature dork. Which, among other things, adds up to someone who does not really have relationships with other people, but instead merely exploits them in various ways. Any nice, sensible girl will get away from you as quickly as possible once she figures out what you're all about; therefore, due in large part to your own character flaws, you will tend to be involved only with women who are just as lousy as you are, or who are too dumb to figure you out. Which means, of course, that you will have a poor opinion of women. It's like a self-fulfilling prophecy.
Fortunately for you, you're young. You have time to improve yourself if you want to, and some of your problems may just be ordinary immaturity. With luck, you'll be a better person in another few years; in which case, you'll find, surprise surprise, that you find more rewarding relationships. Funny how that works.
