One of the challenges I found when it came to groups is when the group suddenly decided "we don't like Becky so she is not in our group so don't be nice to her ok?". I don't like to just suddenly reject someone that never did anything to me but isn't somehow "good enough" for the group. It made me wonder "well, do I have to worry about experiencing that same rejection?". I personally prefer to be free to like whomever I want to like.

This, for me, stems from how my older sister tended to need me to not like anyone she did not like and even wanted me to be mean to whomever she did not like. My sister is the type that needs to own the sandbox otherwise she doesn't like you. That never changed about her either.

So, with a group, it's nice to have friends, but we don't own anyone and everyone should be free to like who they like without feeling they have to only like whomever the group tells them to like. However, it is different if someone joins a group and is jealous and tries to exclude someone who is part of the group that has been getting along well too. The goal is for everyone to get along, like a team that supports and helps each other.

From what you shared, your daughter interacts in a healthy way, doesn't use her wins and abilities to intimidate but prefers to want others to strive to do well too. It's not unusual for a jealous individual to have a problem with the healthy group member. Often, sadly, the individual doesn't realize this about herself either. Most of the time, this person doesn't know how to have a healthy relationship and they don't understand why they are jealous.
