Anyone who follows this advice deserves what they get.
The age old advice still stands: be yourself.
If someone wants you for who you're not, rather than who you are, you are better off just moving on. Here's what I posted on my blog years ago after marrying a wonderful woman I met on Plenty of Fish:
I was recently reading the front page of plentyoffish.com, a dating web site where my wife and I first met (we recreated a joint account to submit a testimonial), that provided a very long, detailed opinion piece to a young man about how to behave in order to win a girl that he was very attracted to. It was from a so-called dating expert, and contained some of the worst drivel that men cling to in hopes of landing a wife.
The given advice was to act distant, indifferent, and aloof; that showering her with affection made him look desperate and goofy. We men turn to this kind of garbage when we're not having much luck with women. We turn to this crap when we actually do become desperate.
It took me a long time to realize what should have been self-evident all along: the old advice of just being yourself is, by far, the best advice you could possibly get. Being yourself isn't intended to improve upon the quantity of women you attract. It is intended to improve upon the quality of women you attract. Not surprisingly, the exact same advice applies equally to women. Don't follow those stupid "rules" such as not making the first move. All those rules are complete and utter crap, and will just make you even more miserable than you already are.
All the little head games and misdirections that you have learned are intended to achieve one thing: a brief relationship. They are not the doorway to a lasting marriage, but rather just the path to multiple meaningless disappointments. You will not be able to maintain the charade you have built, and will always fail in the long run. She will always see through you eventually. You will eventually slip up and expose yourself for the fraud you are, and you will be back to square one.
If she is not interested in who you really are, then you do not want her (regardless of what your hormones may tell you). It doesn't matter how pretty, gorgeous, sexy, or otherwise desirable she may seem. If she is not attracted to who and what you are, then any meaningful relationship with her is doomed. She will eventually (but usually quickly) tire of you, and move on to the next guy.
I am a software developer, and spend most of my time in front of a computer. When I was dating, I tried hard to hide that from my dates. All the advice I had been given was that women were turned off by the kind of geeky guy who spent that much time with his computer. I tried to list other interests on the dating site (tenuous as those interests were), tried focusing on what I thought women wanted, and every other trick I could think of that was even remotely true (and some that were very much not true when I reached a certain point of disillusion). Maintaining the illusion was very difficult, as that isn't who I am.
In the end, it was those very traits that my wife tells me were the most attractive to her. It turns out that her life had been full of too much stress, anxiety, and drama. An easy-going, caring, intelligent, homebody of a man is exactly what she had been looking for, and couldn't find, for a very long time (we were both in our late 30's). She would not have been at all interested in the man I had tried pretending to be, but was hopelessly in love with the man I actually am. Who we really are is what allows us to connect on a very deep, lasting level.
It took us both a very long time to find each other (strictly speaking, she found me), and we both suffered some horrible emotional scarring in our prior lives apart, but that scarring is what allowed us to appreciate what we have together.
So although it may hurt in the short term, it's better to be rejected by women for who you are than to be accepted by women for who you are not. You will eventually find that woman who will love you for who you are, even if you have to go through many painful rejections along the way. The women who accept you for who they want you to be will always desert you. No exceptions.
