Personally I only have examples of long term and solid friendship relationships through the internet.
But back in 2001/2002, when I was playing Ultima Online on the official servers and was hardcore PvE'ing with a mostly British guild, there was this couple who went 'rogue' on us and 'suspiciously' PvE'ed a lot on their own... Everyone noticed that they sympathized a lot with each other, then shortly after a year of long conversations, casual flirting, and an ingame marriage (
), they actually met in real life, one thing lead into another in a matter of months, and they started a relationship. I've lost track of them through the years, but caught them on one of the most popular private shards in 2011, we exchanged Facebook urls and wow, they already have a son, and apparently never broke up. I was stunned to be honest.
Anyway, back to the OP, if you don't want to stress yourself or waste too much time, just go on Tinder, Badoo, Tagged, OkCupid, etc.., and mass spam the 'yes' or '<3' on the match making section without even looking at the pictures. Feel free to call me a manwhore, pardon the expression, but that's what I do since I've had a not-so-good experience. Eventually you will either get laid or find someone you can actually get along with. And with all due honesty and modesty, I've actually got laid once with a beautiful blonde girl after having a 'match' with her, but it all happened way too fast so what I've feared that would happen, eventually happened - it didn't last over a month, and we both went peacefully on our own separate ways.
Apart from that, all of my serious relationships were born on real life: highschool, university, professional acquaintances, and other two I've met in the night life. Just take note of something, I might be wrong since the female mind works in mysterious ways, but if you're going out with some friends and start looking for a woman, focus on the quiet and shy ones, because in most cases those are the ones who are willing to commit themselves into long term relationships. Some wild dancing party goers might be an exception, but it's rare, at least in my opinion and judging from what I've seen.
