I'm going to ditch a messy group
Why would you want to ditch them?
Well, they are often messy and there are some other factors.
Maybe they aren't the right group for you. You need to find one who is better suited for yourself.
I don't feel like I need a new group. Right now, I just want this group out of my life.
It's good that you can recognize when a group is unhealthy for you. Good luck moving on.
