<human>: Summarize the given text in a few sentences.

I'm probably going to sound like a jerk, I know.

I've known this girl (I am also a girl, for the record) since I was in early elementary school, but we have almost nothing in common anymore. She's two years younger than me. I'm in college, and I'm not the smartest cookie; therefore, I have to try really hard and study a lot. She always thinks I'm making up excuses when I say I have to stay home and study, and she tries to force me to do things or go places. I've gotten much better at saying no over the years, but I still feel obligated sometimes because she's been a close friend since I was eight.

Even when I'm not busy, I just don't like to do the things she likes. When I try to suggest anything besides what she wants to do, she finds a way to talk me out of it. She even tries to talk me out of going to GameStop when we're at the mall together. Or she'll go in and complain after a couple of minutes of browsing. I just don't have things in common with her anymore, but she still loves spending time together and refers to me as her best friend. I feel bad for never hanging out with her (which she often points out), but it's just never a good time anymore. How do I handle this? I don't want to do anything dramatic, but I don't want to keep feeling like a douche for not going to her parties or on her impromptu road trips. I suppose there's no easy fix, though.
<bot>: If you don't have anything in common with someone anymore, should loyalty as a friend still come before your personal desires?
