To hate your (former) best friend?

maybe hates a strong word. i strongly dislike him. we used to be best friends. until it just started becoming one sided. he always asked me for favors. but whenever id ask him, he just wouldn't come through. he'd be insensitive and joke around about things ive told him not to. i got him a thoughtful gift for his birthday. for my birthday, i got a print out of a gift i had no use for that was ordered the day before (sorry for expecting something on my birthday, but i was just really stressed cause of APs) i helped him get asb president, but now i regret helping him because hes just irresponsible and lazy (im secretary). he just gets lucky in life a lot i guess. he didn't get kicked out (or even technically suspended) for something (vulgar and stupid) he did on our school announcements (while he was president) than a girl who was kicked out of asb because her teacher wouldn't change her effort grade. he smokes. he drinks. (things i don't do) ive confronted him before about everything, but he just gets defensive. after that point there just isn't much i can do. i just resent him now. for stressing me out so much, for not being there for me when i needed him, for taking me for granted. is it normal or am i just jealous? :(
