Online dating can require quite a lot of persistence. If you have something you like to do, emgage in a related club and truly meet the people that surround you. Online dating can work, so can meeting people doing the things you love.
I used it for two years starting from age 33. I met a lot of girls, had a lot of dates... some of these relationships went somewhere, some didn't go beyond the first date. The trick is to get a face to face meeting sooner rather than later, don't waste more than a week or at the very most two sending messages without having an actual date planned.
