Jealous of ex best friend

[Icantfindausername]

I suspect my daughter who is 12 is jealous of her ex best friend and I don't know how to help her.
Basically she was really close to this girl from 4 to about 10 and they were quite inseparable. As the older girl has got older she's become obsessed with boys and my daughter isn't interested in them yet.
When they started high school they seems to drift apart even more and my daughter now talks about the other girls preferring her ex friend and only wanting to go to the park or swimming if her ex friend is going. She sounds like she's jealous and making everything into a competition. Any ideas how I can help her with this. I personally think she's upset that they are no longer close although when I've tried speaking to her about it she denies it. I want her to meet some nice friends that are similar to her but she doesn't seem to be doing at the moment. Thanks for reading x

I know it’s a bit of a cliche but does she do any sports or after School activities?

Yes she does dancing, netball and gymnastics x

It’s good that she’s doing stuff outside of school. How does she see herself working this out?

She doesn't see there's a problem it's just that I feel she is jealous any competing with this other girl about friendships etc x
