Did I manage this issue poorly?

So after 5 years being together (with a few months of "let's give ourselves sometimes" to fuck other guys in between) my best female friend leaves her boyfriend.

She told us Wednesday night.

Weeks before on a night out she drunkly admitted that she was going to leave him since long distance relationships are shit plus she already has many guys that want to fuck her (more or less her words)

As I'm saying she told us Wednesday night through a WhatsApp group. Apparently noone replied or told her anything since the morning after she ironically said how good friends we were etc...

I need to mention that I live abroad.

Anyway, so the next day Thursday I'm extremely busy. On Friday I have more time but due to the things she told me that night I expect her to be OK so I don't ask her how she's feeling either.

On Saturday another friend asks me if I have talk to her cause she's mad at the people who didn't. I told him that I didn't that I had other things in my mind and that I'm going to ask her now.

I ask her how she's feeling and that I've been busy and couldn't say anything before. Actually I could but I didn't expect this to be such an issue.

Anyway she sends me 3 min long audios last night where she is obviously pissed telling me that I'm a bad friends, that she wouldn't act like this...

Am I being robotic here if I assumed that she was going to be well after the things she told me that night? That's why I didn't care much about this since she already had everything planned...
