We met through both being massively into rock climbing. I had just moved down south for work, started going to the nearest big climbing wall to train and got to know a few people. Somehow we managed to never be there at the same time for the first 4 or 5 months but then one night he was there and it turned out a couple of the people I'd met were friends of his too so we were introduced. I thought he was lovely - funny, good looking, friendly, everyone seemed to like him - and kept thinking about him randomly afterwards. I found out later that he felt it too and made a few enquiries with the mutual friends. A week or so later we met at the wall again, got talking over a particularly tricky bouldering problem and the rest is history - I also found out later that he'd been going there every night waiting for me to turn up so he could 'bump into me' again 
What do I love about him? He's just a really, really good person. He's kind, generous to a fault, thoughtful, loyal, responsible, honest, hardworking, friendly, respectful, just a really fundamentally decent human being. He's also funny, interesting, clever, strong, practical, capable, good looking, fit, outdoorsy and sporty - he's an incredible climber, skier and mountain biker. He utterly adores my dogs and is beyond good with and to them, which is massively important to me, they're really 'our' dogs now. He is not gushy or soppy or sentimental but he thinks I'm gorgeous and funny and clever and he would do anything for me (within reason, he's not a doormat). He makes me feel safe and strong and looked after and capable all at the same time. I have no idea why he was single when we met* but I will be forever glad he was!
*could have been because he snores, has a strange inability to throw away old t-shirts no matter how manky and full of holes they get, can't seem to see dirt in the bathroom and sometimes gets grouchy when he's really tired, but I can live with that
