This is so brilliant. I agree with dead kings, this really is so relatable. The way you wrote it is incredible, I felt bad for both parties and there was really no action from the guy's side other than minimal dialogue. But this was just so perfect and I love how he didn't want to understand why he just wanted to be angry at her.
This is absolutely fantastic, and I think the cherry on top is just how relatable this is. Not (necessarily) the cheating bit, but the bit where the narrator is mentally answering all the questions with everything they want to say. And I think that the paragraph after the "how" is especially relatable, too. And the style of writing is fantastic. It's kind of frantic and hysterical but so calm - but maybe that's just me. Great job :-)
Saw this recced on my updates feed and I guess the title caught my eye. And I'm really glad it did, because this was brilliant.
I love that it seems to tell an entire story in such a short amount of time, and even though we hardly know these characters it's like we've known them a whole lot longer than just for the duration of this.
