He's not your friend if he's ripping you off. Did you explain to him that he was caught? Be like 'Fuck you man, if anyone should be pissed, its me', and get really pissed at him...let him know whats up. You seem kind of intimidated by him. Obviously you and I both know he shouldn't be 'taxing you' or whatever....The real dilemma here is why would your 'good friend' do this to you. Don't take this kind of shit from anyone.
