I did OLD on and off for about 5 years, lots of breaks in between.
I can't tell you how many first dates I arranged, loads, probably a third of which at least cancelled at the 11th hour.
Of those I met (maybe 40... possibly more, it was too depressing to keep count), the vast majority I never saw or heard from again, even the ones who professed to have 'fallen for' me before they'd met me
.
I was variously told I was 'not attractive' 'not girlfriend material' 'a player' (that one because I didn't reply to his texts immediately!), that they'd only agreed to meet me because they thought I was up for it...etc. Not to mention all the weirdos, oddballs, ones who looked nothing like their photos, blatantly lied about their height/ weight/ job/ marital status etc.
Eventually I got to second dates. Had one who was scared of a relationship who kept me hanging on for a few months on and off, and another who became v ill just before I met him, kept seeing me while he was recovering and then once he was largely back on his feet said he didn't want a girlfriend!
After all that, last April I'd nearly given up hope, and had one last throw of the dice messaging men who I thought looked 'nice'. Not super gorgeous, or gym fit, or with amazing photos, but just nice/witty/intelligent.
10 days later I went on a first date with someone who seemed exactly that. When I met him I realised his photos were terrible, and he was really very handsome, and built like a rugby player 
He is now my bf and we're very happy. It took a VERY long time to find him though!
