"Kinda sad someone is prepared to lose their friends over £600"
How exactly do you keep a friend after that? "Hahah, remember that time I lent you £600 and you never gave me it back buddy?! Hohoho"
I'd quite happily lose a friend like that. There's things I would have done differently to the op, namely going around to his house to have a catch up with them and see what the problem is a lot sooner but I'm sure he's done everything he thinks is reasonable.
Ultimately getting the £600 back would only be worth the effort if it was worth my time. I consider my time to be one of the more valuable things to me so I wouldn't be stressed about it and put in as little effort as required. With that in mind I'd be giving your friend as little time as possible.
I think he's referring to the one who received the money losing his friend over £600.
I also agree with the people who said he's clearly going through a hard time, I'd be angry and they certainly wouldn't be my friend anymore, but I wouldn't be trying to make things worse for them.
