advice?

I'm currently a junior and I've been in my chapter since I was a freshman. I really enjoyed it the first two years, but after being away from a summer and coming back I started to feel disconnected from my chapter. I started being more involved with friends outside greek life, school, and work. I still like my chapter, but I feel more disconnected from it now than ever. I feel like so many things are getting old (for example, socials). Is this normal or does any one else feel this way? I'm not really sure what to do from here because I don't really want to drop after investing 2 and a half years, but I also don't enjoy it as much as I used to.
