Man, that guy sounds like a dick.
You should tell him to quit being a dick!
If that fails, tell him to bugger off.
You don't need to change yourself divisionten as far as I'm concerned.
(I bet you're an absolute top bloke in real life! XD)
EDIT: I'd sit down with a nice drink, like a Baileys or a Vodka and Coke, watch a movie and forget about it!
(I never have problems like this with my friends fortunately, probably because I am the most sensible of the lot! Can't help but love the stuff we get into though. Man I wish my best friend would get in touch. Its been over 2 weeks since he was last online, and I'm worried he hasn't got his cool-ass super laptop back yet, and I'm desperate enough to send a text! XD)
EDIT 2: Also I randomly posted "I love potatoes!" in Swedish on the Swedish girl' facebook page today, since her swedish friends were all posting love hearts and phrases.
She's going away soon, which is a little sad, but hey, the worlds not as big as it used to be, so who knows, I may bump into her again.
