<human>: So let's call my friend Steve. We've actually known each other and have been close friends for 8 years. We used to hang out together all the time and we got along very well. A lot of things changed when we went to high school, though. We went to separate schools and I kind of figured that we would both become different people but I hoped we could still stay friends. Now, neither of us were social butterflies but high school has allowed me to come out of my shell more and become a much more social and confident person. It did the exact opposite to him, and I'm not sure why. He never really wants to do much other than play video games and all he ever talks about is obscure animes. I can't remember the last time I had a discussion that wasn't about anime with him. In addition, he's begun to act very arrogant and it can easily get on my nerves. Our personalities clash way too much at this point. I feel kind of bad for feeling like this but it's becoming more and more difficult for me to hang out around him. So, what I've been doing is just trying to distance myself from him. I'll just try to avoid discussions with him when we're hanging out and if I do have to talk to him, I'll just give very brief responses. I don't have the banter with him that I do with my other friends. I can be very witty and very (jokingly) insulting. That's how you know you're a friend of mine. But with Steve, I'll just treat him like one of my acquaintances and be very polite and boring. I'll come up with excuses not to hang out with him and I feel pretty bad about it sometimes. We've been friends for so long and I'm one of his only friends (like I said, high school made him become less social and outgoing) but he's changed into someone that I don't really get along with very well. Am I an asshole for trying to distance myself from him? Is there a way that I can try to change him somehow? Although that doesn't sound like the right thing to do.

Summarize the given text in a few sentences.
<bot>: Childhood friend of mine doesn't get along well with me anymore and I want to distance myself from him, but I am one of his only friends and he isn't very social at all. Am I in the wrong for doing this?
