What's an unspoken girl code rule you'll never break?

I recently stopped talking to one of my guy friends after he and one of my close girl friends broke up. He's been a good friend and my friend even told me it was completely okay if I stayed friends with him.

But it just didn't sit right with me. It went against my own girl code rules.

It got me wondering what girl code means to everyone else.
What are some unspoken girl code rules you always follow?

I'd love to hear them so I can keep showing up as a better friend to my girlies. 🩷
