You'll probably have to kiss a few frogs before you find a soulmate, but I know what you mean about tindr and stuff! Feels a bit full on doesn't it? I couldn't go for that stuff either when I was single.
A gamer bar local to me does "geek dating' nights. That might not be relevant to you but for people into video games its a great way to meet like minded people! Doing things like that can be good
Lots of free dating sites, some people on there don't want relationships but you'll be able to see that on their profile.
The Guardian has their own dating thing, I've not used it personally but a few of my friends have and they said it was really friendly and nice.
Good luck
