In reply to gaucho: If you're belaying your boyfriend, you can:
- make sure you're concentrating the whole time
- take in what slack you can (as you did)
- point out gear placements
- shout encouragement
- tell him which rope to clip when climbing with double ropes
And so on. If you're not there you can't do all these things to keep him safe. I'd imagine after a fall like that it'll be a little while before he wants to do routes like that again, so that gives you time to get your head together again. Keep climbing and talk to him about how you're feeling!
