Do you think I did the right thing to do?

No you shouldn't go back to your old friends, there obviously immature and you should be the bigger person. This has happened to me way back and the "queen bee" girl who talked badly about me ended up later talking badly about another girl in the group and betraying her. You shouldn't care what ppl think, start hanging out with other people get to know the other groups. If you are a nice person and fun to be around I don't see why other people wouldn't want you around. Don't go around spreading bad things about that girl tho, like I said be the bigger person and u will find some true friends.
