i made him get mad with me .

recently i felt disappointed with someone who play an important role in my life. due to some reason, he made me feel don't want to talk to him, and don't even want to let him know where am i. just now, he whatsapp me and ask where am i, i just simply answer him with 'where am i is not important'. i think he has get mad with my answer, and he said the way i answered is so rude to him. even i know i shouldn't do that, but sometimes when you are disappointing with someone, you can't control your mind, and everything from the person come to you, you will feel uncomfortable, and you will not treat him well in talking or whatever. maybe after a certain time i should apologize to him, but right now, i really don't want to talk to him so far. am i so bad? ^^
