I'm in a terrible misery....please advice me what to do?

just don't care about what he has done to you,he feel insecure now and jealous to you because since then he was the brightest than you but now you over take him,so what you do stop talking to him for awhile but leave him a message just saying that you want to stop arguing with him because you feel bad to me and i can't help it.,just to be frank to him that you feel hurt the way he treat you.that's it don't talk to him until he realize that he is wrong.for treating you like that,
