Friend is an ass

Ok, so this happened a long time ago, but i'm a guy so i usually keep my feelings in until i can't stand it anymore. When i was around 9 years old (I turned 20 this month), i made a friend with this guy who lived down the street from me. It turned out that we both had a lot of the same interests like tv, video games, and stuff like that, so we soon became best friends. Our parents even began to hang out with each other and they also became good friends. It seemed like everyday of the week one of us was over at the other's house, my parents became like a second set to him, and his parents became like a second set to me. It was all fine and dandy, until my junior year in high school when his mom's grandmother died and left her a decent bit of money in an inheritance. With the inheritance, my friend's parents moved to the other side of town, but they've remained in touch with my parents. Since I just got my license at that time, I was able to drive to his house and hang out, but if we ever wanted to do something, I was always the one driving, and we always took my car, even though he had a car and license. But I didn't mind, because I was still hanging out with my friend. After a while, I'd make plans with him to go to see a movie about a week before and he'd say that it was ok with him and then the day of, he'd cancel on me. One time, when the hangover was going to come out, I asked if he wanted to see it with me the day before its release and he said no, that he was just going to stay at home. So the night the hangover was released, my parents went over to see his parents so i asked if he was going to be there and his mom said that he went to see the hangover with some of his other friends. I'd also ask him what he'd be doing one weekend and if he wanted to hang out, but his answer would always be something like "if no one else wants me to do anything" which is a completely ass%o!e thing to say in my opinion. He made a lot of new friends who had money and eventually got a girlfriend who had him completely whipped and if I ever asked him if he wanted to do something, no matter when it was, he'd always say that he was going to be with her (they've since broken up). Then, about 7 months ago, when he still had a girlfriend, he had to get a wisdom tooth pulled and his girlfriend didn't want to take him, so he asked me to give him a ride to which i said yes so his mom wouldn't have to take off from work. I decided to take my dad's truck because it was below freezing and he just got home from his job so the truck was still warm. So when i go to his house early in the morning on one of my precious days off work after only about 6 hours of sleep (not nearly enough for me), I tell him that we're taking his car as I don't want to waste my dad's gas. Upon hearing this, he got p*ss*d off and refused to let me drive his car. He basically threw an 18 year old's version of a temper tantrum. After a while, he finally decided to relent so he wouldn't be late to his appointment. So we get there and he gets his tooth pulled, and when he gets back to his place, he acts all pissy towards me, so i decided to leave. Since then, the only time I've seen him was at his uncle's funeral and he came up and started talking to me like everything was cool, but i couldn't act like an ass towards him because his uncle just died. That was about 3 weeks ago and i haven't heard from him since. Sorry it's so long, i just had to get all that off my chest.
