I was really "the Ultimate Prick". I mean I used to treat everyone like dirt and I thought that I was right for doing so! After I was about 17 or so, it started to taper off, I was more kind to people. By the time I was in my early 20's I was really polite to most people.......but now I think I may be slipping back LOL!
Anyways, what Im saying is that I dont think he's right to be acting the way he does towards you, and of course you dont have to take his behavior lightly. He is gonna have to figure out if he is brainwashed or not! His Father may be telling him lies about you and thats a shame, but he will eventually begin to see that these things are not true, then sooner or later he will begin to mellow out. Divorce is always hard on kids (I said "hard on" hehehe), and boys usually stick to the Fathers side, while girls stick to their Mothers side....I think its kind of genetic or something. Certainly, there are exceptions ( I knew a girl who stuck to her Dad, and hated her Mother....go figure!). Stay on your course! try not to get into heated arguements with him, if he wants to argue and yell, tell him the discussion is over until he can speak sensibly to you without raising his voice. Put your foot down! dont let him try to bring stuff like "Dad said this" or "Dad said that" against you. Because he has "ammunition" to use on his side against you. If you refuse to play that game, he'll be forced to confront you with his own issues that are not from his Father.
Also, DONT COMMIT SUICIDE. If you think he hates you now, then he will REALLY hate you for doing that! because he will never have the chance to make up with you, and his only memories of you would be bitter, hateful memories. Besides, its automatic eternity in hell for ending your own life.
