You're defeatist, OP. Mr Perfect isn't going to put his arm out to stop you falling in front of a bus, and then issue you with an oily 'Hey babe, what's your number..?'
How do you think people meet usually? It's mostly at work, where people are simply put in the same place at the same time, and someone seems really nice. Nobody has to 'chat anyone up'. But it's perfectly possible that you could get talking to someone, isn't it, in some random way? Someone who isn't letching, and is just a decent bloke on his break from work or picking up some pasta in the shop? It does happen. I know a woman who met her husband in a pub car park. He'd had one too many and had fallen into the hedge! They're so happy, years on. I know a couple who met in Sainsbury's, and had their first child 9 months and 2 weeks later; she's 22 now, and they're still always happy.
I met my partner through OLD, but I only logged on to terminate my subscription because the whole year I'd paid for had been useless and I didn't want the company emailing me or charging me again. My partner had logged on to use the 'hide profile' function, having had a similar experience and lost interest.
It happens all over the place all the time. It happens when people have been single for a month, a year, 5 years, 10 year, all their adult life into their 60s. It just happens, and the more people you meet, the more likely it is to happen. If you meet people who are desperate to date, then they have a greater chance of not being ideal partners, because they dislike life alone, and if they don't like spending their time with just them, why would you?
