How can I stop this?

I apologise if the following is confusing but I'll try and make it short.

My best friend and I are like sisters, except lately I feel like I might lose her.

My best friend (J) became friends with two other girls (K and G). When that happened we did had a little fight, because she started ignoring me for them a lot. We made up and everything, and if anything I think it bought us closer.

But in the past month my best friend and K decided they didn't like G anymore and there was this huge fight between then and now they hate each other.

I've become good friends with G, while my best friend and K are good friends.

my best fiend and I spoke about it, and we both agreed we wouldn't let K and G hating each other get in the way of our friendship.

EXCEPT, the last few weeks I've hardly spoken to my best friend. I really don't want to be clingy and text her so I've just left it, but it's been over a week. We've both being having out and partying with two different groups of people because K and G don't want to be together.

I'm just upset because I don't want to lose my favourite friendship over someone else's stupid fight.

I was thinking about texting her, just being like hey, what's up? But like

I said before, I don't want to be clingy and she clearly doesnt miss me because I haven't heard from her yet!

What do I do? :(
