Friend drama

I recently got invited out to dinner with some old friends that I didn't really want to see anymore. The three of us used to hang out a lot last summer, but we fell apart with busy college schedules. I have been friends with friend A since middle school. She and I used to be super close, but I feel like we don't have much in common anymore. Friend A is very talkative so sometimes it's hard to get a word in with her. Sometimes I didn't click with friend B very much, but at other times we were close. I felt like she always was more into my other friends than me. At times friend B can come off as snobby. I used to have a lot of fun hanging out with the both of them so I'm considering going to dinner with them, but part of me also wants to just let our friendship fade out. What should I do?
