Why are only drama queens available in the dating world, Why not the real or normal ones?

I never dated anyone in my whole life of 38 years and by migrating to USA 10 months back, I thought to give it a try. And within 48 hours of my date with someone from Yahoo Personals, I fell in love. That might look so childish and so immature to anyone but since I was so much full of life myself and so much positive about everything around me, having been on top of everything in life, I never thought I'd fail in loving when I started dating her. And now, after this breakup with her after 5 months' affair, I have a feeling that there are only drama queens available online to date. Rest are busy in their positive and constructive lives. Am I right or are there "real" and normal ones out there available for dating via websites? I don't drink, hence I can't socialize in bars and clubs. However, I've a large number of my website members, 10,000+ with females being majority. But to them, I'm a noble figure and if they find out that I'm dating, they'd think low of me :) My co-workers, I've a policy of "no drama" in office due to that being the financial lifeline and too serious thing to be involved with something risky like dating. Can I just walk into any suitable woman and ask her for a date? I mean I am so much shy and so much full of self-respect, that even thinking about that, makes me scared inside. So, I'm stuck, any help?
