Life Isn't A Game

Lately I've gotten really sick of the crappy dating stuff going on for myself, my friends, and people I know. Granted this is about guys, and I'm not saying girls don't do bad things too (cuz they totally do), but this is from my perspective. Anonymous stories but I promise they are true.
1) A girl met a guy in class and they hung out after. They held hands a couple hours later and although that is really fast, he made no move to kiss her when she left so she wasn't worried he was only in it for that. He started talking to her a lot and showing a lot of interest. The next week he suggested doing something after class if he was able to. She sat down in class, he came and sat next to her, and another girl came and sat on his other side. She started putting her hand on his leg, playing with his hair, grabbing his hand, writing stuff on his back for him to guess...you get the idea. After class he talked to that girl and her friend and left without saying goodbye.
2) A girl decided to open herself up to a good friend who had become extremely interested in her. Things went wrong from the start when he wouldn't completely commit and suggested they date other people. Neither of them went on other dates but after a short while he ended things with a reason he should have known before he started anything with her.
3) More than one guy I personally know will date a girl for somewhere around two weeks, drop her, and immediately have a new girl. Even to the point of this: cuddling and holding hands with girl A and the next time she sees him (a couple days later) he is cuddling and stuff with girl B, but he never broke it off or said anything to girl A. Another of these guys is even a little scary about how obsessive he is over whatever girl he has at the moment.
The moral of the story is that this kind of treatment isn't okay! In situation one, the girl got lead on and burned pretty bad. Holding hands obviously meant basically nothing to the guy, but to most girls (like this one) holding hands DOES mean something. But these types of guys have to realize that when they hold hands with a girl and show a lot of interest, yeah the girl is going to think he is interested! Also, guys always say they can't stand "those kind of girls" that are all over them, but look at this situation. He soaked it all up, even when the girl he had been showing tons of interest in was sitting right next to him.
In situation two, the moral is don't start something with someone until you're sure it's right and you're sure you want to. This guy could have saved a girl's heart and their friendship by just staying friends.
The third situation is perhaps the most irritating to me. These guys think it is okay to bounce from girl to girl to girl with no thought of what they are doing. Let me give you a hint: when you meet the new hottest girl, don't just pounce and start dating her immediately and then two weeks later realize you don't like her. It would save a ton of trouble if these kind of guys would actually get to know a girl before they decide to date them. Wow, what a radical thought it is to actually know someone before you date them.. Having flavors of the week is not okay. Plus watching this from the sidelines, my friends and I have lost respect for these guys and would say no to a date with them without even the slightest hesitation. What is going to happen when these guys decide to they want to settle down, and realize the new hottest girls out there may not be what they want in marriage, but the girls they have known and trusted for a long time refuse to date them because they don't want to be the next flavor of the week? Good luck with that one. And honestly, what are these guys getting from doing this? A bad reputation, hurting girls, losing respect...is it worth it to have every girl you want every other week?
Life isn't a game, and people need to stop playing with other people like toys. The end.
