By your own admision you were doing all that to get into her pants. And you resent her because your first tactic didn't work. Behaving like a friend when you want to fuck someone is also a lie.

So she basically realized that she would lose her friend when she saw you were going to be with another and decided to give it a try.

Now let me give you another perspective. I'm going to quote you "countless men lie to get into your pants and somehow are better?". From our perspective you were also lying to get in her pants. Because you behaved like a friend would do, but wanted to get into her pants. That is a form of lying.

The other guys that you are critizicing, do the same. They compliment, claim to love you or whatever it takes. Some girls and women do believe those lies. At the time they think those are good guys. You resent them for trusting other men and not you.

Does that sound as being nice? If a woman cheated on you and you believed her lies, should another woman who has been acting as a friend resent you for believing her?

It all comes down to: were you a real friend or just wanted to be close? Was she a friend to you? Did she listened to you? Care for you when you had a problem? Because all those things meant that she was being a friend to you. The "dreaded frienzone" means that the woman is taking you at your word, believing that you want to be friends and not just date. You resent her for giving a try to take you out of the frienzone.

Well, now the harsh truth, maybe you should break up with her. If you resent her, the relationship won't go well. And you should be more honest with yourself, you are the one who can handle a friendship with women. And let me be painfully honest, yes we can handle a frienship with a man (we also acts as friends but nothing more), and a man acting nice to get into our pants (once we identify that they act as friends only to get into our pants, they are no longer considered nice because is a lie).

The problem is that we don't handle it the way you want, because being nice won't guarantee sex or dates. Sex, dates or a relationship require more that basic respect. And you are right, we do treat others as we want to be treated: as friends. Sadly, many men who treat us as friend, aren't treating us as they want to be treated: as boyfriends. And for a relationship, many of us want to be treated as partners, which is also different from the idea of "girlfriend" many men have.

And if you don't understand what I have explained, turn it around and think about a "gold digger". One who behaves as the perfect girlfriend to get close to you. Who behaves as if she was madly in love with you, only to get your money. That is basically what you did. And you were succesful. Maybe another men like you is resenting her for dating you, since you obviously lied to get into her pants. Ironic, right?
