Thanks for all the input guys, was really helpful.
For anyone interested I'll conclude.
When I saw him yesterday he actually apologised to me.
Apparently this girl has done this to him before, she leads him on, then sleeps with someone close to him.
He was obviously a bit upset by it all but we man-hugged, I apologised, and we should be good now.
Don't think either of us will be seeing that girl any time soon tho, which is a shame as they seemed to have a good friendship...
But then I suppose is one side of a friendship wants a relationship, and the other doesn't, it wont ever work :/
But at least we are still bros

Thanks for all the good advice.
And yeah....
