I am starting to hate girls/women?
"I am starting to not see women as people, but more as objects." This is the root of your problem. ALL women, no matter how beautiful, smart or talented were at some point a young girl that belonged in a family. They see themselves as only people. They don't see themselves as objects of desire. So, treating them as anything else will be off-putting to them. Next time you see a woman that you're very attracted to, try to forget that she's so beautiful and approach her as if she just another person that you meet. Be nice, attentive and interested in her as a person, and you will find her very receptive to your flirtations. Trust me, she's very tired of being approached as if she is some prize to be won. Your new approach will be refreshing and interesting to her. I have always had very beautiful girlfriends, one was a runway model and two of them were lingerie/swimsuit models. As with my current wife, who is probably the prettiest of them all. The way that I was able to date and keep them was using the attitude I just described to you. Women are just people. Of course they are different from men and require a different approach than making friends with a man, but the attitude is the same. Once you see them as just people, you will actually start to LIKE women. Once women can see that you like them, and their ways, they will be putty in your hands. Because there is nothing more appealing to someone than someone who seems to like everything about them. I think what you should do is to STOP looking for romance for a while, and start making friends with women. Start to get to know and understand them, and you'll find that they are wonderful and interesting. You'll start to like them as a gender, and they, in turn, will start to like YOU. Then you'll find it easy as pie to make connections and have whatever kind of relationship you want with them. From casual sex to marriage. A woman will give you whatever you want if she knows that you like them as a person and approach them correctly. So drop the attitude and learn to enjoy the ride.
Why do guys treat certain girls like sexual objects?
It's complicated, but the blame lies on both sides. Some women make bad decisions for various reasons--Lack of experience, early trauma, daddy issues, whatever. They make such bad decisions that certain types of guys will be able to pick up on that and pounce, like a wolf on a sheep. Not all guys are like that, same as not all girls are either. But if you find yourself constantly being humped and dumped, then ask yourself what you're doing to put that out there. While that might sound like I'm blaming the victim, think of it this way: If you don't change your actions, your life will always be this way.
What does "Treating a woman like an object" actually mean?
I wish it could have meant treating women as if they were not human. Sadly, feminists use that expression to criticise straight men who look upon women as potential mates. This they find demeaning, since women should be able to get on with their lives without men, except as playthings, sperm donors, and providers of what they can get perfectly well themselves, thank you. Edit - TU for Fizz's answer below me that does put the other side. At what point in human evolution are women considered chattel, rather than an equal half in a sexual union and partnership? And does the term "my wife" or "my girlfriend" always imply ownership or possession, rather than proud association (as in "my country").
Do some women that are only used as sex objects, bring it on themselves?
People have to have self-respect in order to expect and demand to be treated well by others. Most women wouldn't say that men used them as sex objects because we wouldn't allow that. If a man treated me as an object rather than a companion, I wouldn't spend time with him. So in the obvious sense, yes, she brings it on herself. But if you want to delve deeper into what caused her to have such a lack of self-respect, you could spend a whole lot of time apportioning responsibility for the situation. I'd say it might be better to just acknowledge that this is not the ideal relationship for you and not worry too much about who's to blame.
