A true friend would have never acted the way he did. You might seriously want to reconsider your choice in friends, OP. In the meantime, good luck getting your money back from that prick! =)

king hit the c*nt and take it from his wallet

When you get your money back I wouldn't talk to that "friend" again if I were you, OP.

Well seems like he isn't a friend now. So he must pay.

Be careful who you loan money too... Some friends may seem sincere, but there are many selfish people out there. Still hope your friend decides to do the right thing OP!

Ask him if you can "borrow" £260.

sounds like he's more of a best friend

Kinda YDI for having such a friend and giving him such a high amount.... Also FYL because you might need it. Kinda been there. I preferred to lose the money and ditch the "friend".

Borrow £10 from him 26 times.

Friends don't have to be asked, to pay back. Drop him like a bad habit and take this as a lesson. Friends and money don't mix.
