How do you handle when a girl asks why she got soft nexted.

Girl I’m seeing called me pissed off saying I ghosted her. I responded to her telling her I was busy and I just fell asleep. She kept pushing so I said “because I asked you to do XYZ and you didn’t”. She then asks me why I couldn’t have just told her that and that now she’s pissed and feels like I ghosted her.

I told her that this is important to me whether or not she agrees and that’s my expectation. We keep talking a little bit as she tries me to get to see her side of the story, which I don’t entertain at all. She then says this is bullshit and then hangs up.

Your take?
