Relationship

i have a friend .. a net friend .. who happens to be the friend my schoolmate.While chatting we bonded very well then he proposed me but i refused ...still we are in touch with each other. but i have noticed one thing that he always tries his level best to prove me that i'm useless..never appreciates me for anything.. compares me with my cousins even went to the extent of showing keen interest in making friendship with them...often says my cousin is everything he wants to see in agirl ..when i encourage him to go ahead with her he becomes violent ...says i was joking then agin hurts me. for no reason he wud say i have complex ,i'm good for nothing ..even blames me for my previous failed relationship.i want to know why he's doing all these things????

It makes him feel better for a while, but never accept to be badly treated by anybody. Skip him and try to find nice friends.
