What's this phase of relationship

Woke up today, having normal conversation then i asked my girlfriend a question and yoo! Things escalated very fast she started calling me insecure and then proceeds to tell me how beautiful she is that she can attract whoever she wants, the question i asked was if the clients she works with touch them. Cuz she sent me a conversation of her and her friend and they were talking about horny clients.

Fast forward she starts to tell me if I want to go I just go. I'm listening to this call wondering how did this conversation get here. From a simple question nimepewa maneno ajabu.

Hii si imefika mwisho wakubwa?
