Ok, this is slightly off topic…so I apologise for that. However based on the conversation so far, I have to ask:
How much do us girls honestly trust our female friends?
I’ve been asking myself that all morning and I still have not come up with an answer… which in itself is very telling.

Let me add one more thing about trust and friends. If you get into a random fight and your ass gets kicked in that fight, then don't expect your friends to get into that fight and save your ass.
This is an absolute given, as long as it’s one on one and both participants want to fight…then everyone else should stay out of their personal business. But if 2-3 girls were squaring up to you, would you trust your friends to step forward and have your back?
When I ask myself that question my answer is perhaps, maybe…
After what happened to me once, I'm not sure if my friends would get into a fight, even if 2-3 girls attacked me. Three years ago, I got into a drunken fight against a bitch. I was in the company of 2 of my friends and this bitch was in the company of her friend. We fought 1 on 1 and it was fair. But it was very bad that at the moment when I had already lost and was lying beaten on the ground, this bitch continued to beat me (she literally punched me in the face and head), my friends did not even try to stop this fight. They were just watching that bitch smash my face. After the fight, they told me that they did not try to stop the fight because they were afraid of being beaten.
It's very sad to hear about this.
At least now I know what to expect from these two friends in an extreme situation. But I'm still surprised by the cowardice of my friend, who is almost 180 centimeters tall and weighs 75 kilograms.
But was it really cowardice or secretly she just didn’t care?
It’s an impossible question to answer I know, but based on everything you’ve said about your experience. I feel for you and I’m struggling to reconcile your friend’s inaction and if the same happened to me. Me and my friends would have had words at a later date, I’m not saying we would have had a fight. But we definitely would have had an argument about the events of that night.
And yes…I am bitch.
I've known her for many years and she's a good friend in other situations. She's not a conflicted person and she's not used to getting into fights, unlike me. So I'm sure she was just scared.
I didn't seriously quarrel with them about this situation after the fight. At least they helped me get to my house after the fight. Considering how bad I was and how badly I was beaten after the fight, I needed their help in this
Don't worry about it, I'm a bitch too. 
Great, you're bitches and I'm a cutie. 
Now, seriously. Girls, what about you? Would you come to your friends' aid? Would you get into a fight?
It depends upon circumstances.
But if she is outnumbered then of course I’m stepping in. As a rule however I don’t like interfering in other girls catfights and I would go nuclear if someone interfered in mine.
But if something was going down like what happened to Ruslana, then of course I will act.
So it turns out that Sasha is a cutie, and Kate and Ruslana are bitches. Now I'm going to go and tell everyone I know about this. I guess that's how gossip starts. 
Kate, I think you're setting too many conditions. It seems to me that you are confusing an organized fight and a fight that arose spontaneously. If the girls agreed to fight one-on-one, then that's their business, of course. But if a fight broke out, I don't know, like in a bar, when some drunk bitch attacked your friend, are you just going to stand there and watch? You're saying that you don't like it when people interfere in your fights, meaning that if you're lying on the ground and some bitch is kicking you, there's no need to interfere? I don’t know if even a stranger was being beaten in front of me, I would have tried to stop the fight.
Although, to be honest, in the heat of a fight it’s hard for me to stop; I can easily land a few blows on an already fallen opponent, and I’ll be grateful to my friends if they pull me away from her before I cause serious harm to her health.
As I said at the start of my previous answer, it depends upon the circumstances. Which was honestly me being lazy with my reply…I had just got up and had not had my morning coffee. I don’t function so good without it

If my friend is a willing participant, then I’m staying out of it. But I will watch her back. If she was not say a willing participant then, I will act.
If I was on the floor being kicked and stomped into the dance floor, if I was utterly defenceless? Then of course I would be grateful for any proverbial white knight. But when we reach this stage, it’s not a fight - it’s a beat down and my mind separates beat downs from fights. If I’m in what I judge to be a fight, fuck yes I would go nuclear if a friend interfered.
If a friend interferes during a beat down on me, that would be hugely out of character for them. The sad reality is that if they saw this happening to me…I can name three who I’m certain would be making fucking TikTok’s. As for the others, they would act…I’m sure of it, well kind of sure. Definitely most likely…assuming of course they didn’t have more important problems. Something urgent like a broken nail

My friends are great for a spa day, even better for a day of shopping and dinner together. But do I confide in them? Hell no, the minute my back is turned those juicy secrets will be sent to a plethora of what’s app groups. Do I trust them to have my back on a night out, I don’t know…I really don’t know.
