Can't seem to attract a girlfriend and I'm really getting depressed?

I'm getting so tired of this. I'm 32 years old now and haven't had a girlfriend or ual relationship for years now. And I don't understand it. I'm a good looking guy, with lots going for me. Good job, gaining wealth, responsible, driven, honest, have many interests that I am pionate about, and I'm overall an exceedingly good person. But it doesn't seem to be enough. Women in general seem to be ridiculously picky with unrealistic standards, and the slightest flaws seem to be dealbreakers. For instance, I consider myself to be plenty confident, but shy and quiet, which seems to be my achilles heel. They aren't willing to put up with a little initial shyness and a few awkward silences to wait to see what good things lie underneath. It seems to be a dealbreaker time and time again. Yet I see guys with much less going for them than I have and they are gainfully involved with great women. I rarely meet single women who seem interested in me initially. Often, I'll give a friendly smile to a girl stranger and most of the time all I get back in exchange is a dirty look, or a sharp look away. Other times I break out of my shy shell and try to start friendly conversation with a girl stranger, and the vibe i get in return is "why are you talking to me?" Many women say they want a confident, nice guy to approach them with a "hi!"...but in reality it never works. Paradoxically, sometimes a girl stranger will tell me I'm cute or have pretty eyes, but then will act uninterested when I try to start friendly conversation with them, as if I have somehow disappointed their expectations of me. On the rare occasion that I do get a date (usually through an introduction by a friend), they seldom continue to show interest beyond the first or second date, and usually I never see them again, or they continue talking to me on phone or email but blow me off every time I try to set up another meeting. Happens time and time again. Yet these same women end up sleeping with some other complete zeros at the drop of a hat. It makes no sense. Everyone says "don't worry, be patient, the right one will come along sooner than you think and appreciate who you are." I've been waiting for YEARS. Nothing has changed or improved. I've done everything I know how to do...put myself out there in the middle of as many social situations as I can find, show interest in girls I like (being very careful not to come across as desperate or needy), and I get either rejected from first eye contact, or kicked to the curb after the first date or two. What are women looking for that I don't have? I honestly don't know, and none of my friends or family seem to know either. Women seem to want it all, most of which I have, but still, the slightest dumb comment that comes out of my mouth, awkward silence, or whatever other trite flaw is enough to disqualify me and eclipse all the good stuff. Yet I see guys with virtually nothing going for them with women whom I would die to be with. The frustration is supreme, you can't even begin to imagine. And there are times when I want to just give up. It's really been affecting every other area of my life, in a bad way. Everybody says "women are attracted to confidence." As I said, I think I am amply confident, I'm not Eeyore. But on the other hand, how can one expect a person to maintain high confidence when they are faced with constant rejection? I think I have been exceptionally strong in spite of all this, and have pulled myself up by my bootstraps...but still, I get kicked in the nads over and over. I don't know what more I can do. I appreciate you for having read my rambling stream-of-consciousness thoughts. Thanks.
