i've learned english for five years in the school and college as a student. i couldn't find out the single word used for the following example....

as example: "my friend has a car and we went to see the exam result by that car together. we everybody got result but what wonderful thing was my result was the topper. in the time of returning my friend denied me to get on his car due to hihg scoring in the exam. He took all other friends but left me lone."

so in that case what we can say in a single word in what case my friend denied me. it seems slightly different of hatred and discriminate. so any other single word to use in such case in english? pls get me know it. thanks.
