I'm going to choose to be with a new friend group that I relate to more rather than the friend group that I have a longer history with.
Do you think this new group is a better fit for you?
Yes, I think I'm more compatible with them and they're more understanding than my old friends.
Choosing the right friends is very important. I see no issue with your choice of actions here.
I had a chat with my old friends and they said that the new group wasn't the right group for me.
Your old friends don't know what's best, only you know that. You can still be friendly with your old friends, but I think it's a good choice to be with a group where you feel like you belong.
