Well, after a few days of moping and feeling utterly rejected, I have picked myself up. It's a bit stupid, but it may help you too, Itjustdisappeared.
What upsets me is not finding out how it ends. With OLD, it's so brutal, someone disappears and you never see the other person again due to having no mutual friends.
I imagined we went on a few more dates, it didn't really work and we both decided to call it quits. It sounds really silly but finishing the story in my head and ending it in a way that makes more sense to me personally has helped me put him in a box and feel happier.
Interestingly, you can totally manipulate Bumble (now that it's working for me again!) into finding out what sort of men have already swiped right. The answer is younger. 
Applying the age old rule of divide by half and add seven, there are still quite a few boys who have swiped right who I feel are too young for me...
I wonder if it's because younger men prefer me, there are more younger men on Bumble or because younger men are more inclined to swipe right to everyone? I still haven't met any mind, everyone I've met up with has been either my age or a little older!
Here's to a glorious weekend everyone, with lots more dates, looking for dates and generally feeling fabulous about ourselves. That goes for you too, Itjustdisappeared. You know you deserve better. Finish the story, move on, look for a new iron. And yes, I know that advice is bloody hard to follow when you're still hung up on an old iron and wondering what the hell happened. But even if he replies, you deserve so much better than someone who isn't that keen on you - go looking again!
