In my mind, I’ve made it abundantly clear what I want.

Every sentence that starts with “in my mind” is not objective, therefore there is no fault in a faulty translation by the interpreter. If you want to be understood, you can either try to be clearer or give up on the responsibility of being understood. And if you give up on that responsibility, you cannot complain about the outcome of said communication.

You’re either not paying attention, or not focused on me enough to hear what I’m saying

This is an extremely narcissistic way to view relationships: if I’m not focused on you it means that I
A) have something more important to think about
B) I have not understood the gravity of the situation and that can be corrected
Of course if I think something trivial is more important than you it might be a problem, but this is hardly ever the case

now I’m mad enough that I fear I will start an argument if I need to spell it out again

Not talking about it is a wonderful way to start a bigger, heavier argument later
