He just replied!
I'll try to translate it...
I know I shouldn't have, but I replied (he managed to irritate me enough, the manipulating genius that he is):I'll be brief too then: you are a huge bitch! I really can't understand your metamorphosis. Anyway, I am unable to hate you because of the good you did to me, which you now want to renounce. You'd love it if I hated you, wouldn't you? I'm sorry, I'm not gonna give you that satisfaction!
As far as I'm concerned, I'm done. You "don't want to talk about those things", go to hell, you and your asshole attitude!!
I reeeally hope that's the end of it!!...I guess we can't be friends after all XD. At any rate, I'm glad I got the chance to explain myself. Bye bye!

Update: no, he replied again. He said I didn't explain anything and I was just too afraid of talking about sh*t... He is seriously messed up. I told him I explained the REASON we can't be friends, and that judging by the way things are going, I was right. I told him to re-read my e-mails if he didn't get it the first time, because I wouldn't repeat myself yet again.
WHY doesn't he just get it??!?!??! Drives me nuts!!
