have you looked into the cost of living in London?
We have had time to get angry over it, and trust me i am fucking angry, but the best way is to make him look like a dick.
Revenge gets no one anywhere, and violence doesnt either. Trust me, i am 115kg + and a boxer, so would be easy to resort to that shit, and he is probably sick with worry thinking that is going to happen.
Plus side, looks like his missus might have left him too while we were away, so this will be more shit on his plate to deal with.
Best to just walk away and leave the others to deal with his shit.
then, maybe, just maybe, in a few months time take out some revenge...
