Ruby is focused on her mission with JNR, has them to keep her company, and didn't expect to be gone so long. Actually, Ruby is the only one we've seen show any sign of missing any of her teammates, but it's easy to miss. I'm guessing you missed it. At the end of The Next Step, as Jaune goes over the checklist, he says "Ammo", Nora says they're fully stocked on ammo and says "Thank you, Schnee Dust Company!", and Ruby frowns and gets a distant look on her face like she's thinking about Weiss.

Weiss has been moping at home, mostly in her room, and is focused on dealing with her father.

Why would Blake regret leaving her friends if she thinks leaving just saved their lives?

One of the reasons Yang put the prosthetic arm on is because she realized that she was holding Tai back from looking for Ruby because he felt that he needed to take care of her.
