Need some help on how to help my 14 year old DD. She has had a friend "Girl B" since primary school where the friendship has waxed and waned. They fell out at the end of elementary and my DD was excluded from the group. Some of it was my DDs fault, but the girls in the group were also to blame. She worked through it and entered middle school in a largely healthy place. Girl Bs group in elementary also imploded and she went on to make new friends. They had separate groups and Girl B and DD were not friends.
Girl B came back into my DD's group beginning of this year and here we are at the end of middle school with exactly the same dynamic. My DD had a falling out with this girl again and now she has once again pushed her out of her friendship group.
Im working with DD taking responsibility for her many mistakes, but there seems to be a dynamic where Girl B is almost sort of stalking DDs friendships and ousting her from them. Obviously, DDs friends are not great if they can't support her and I have asked her to stay away from GirlB. She says she needs to be friends with GirlB or the exclusion will be even more.
Part of the issue seems to be that DD and Girl B both are/ want to be friends with the "popular girls" and its almost become an unhealthy competition and one DD is losing.
How do I help her break this cycle. Ive tried talking to her about true friendships etc and how she has to be a good friend to get good friends but she seems to be trapped in this vicious cycle of chasing popularity etc
Im trying to get a therapist for DD but are there any good books or resources I can use to help DD.
ps Im in the US
