During a heated argument, jill explained, "from my perspective, i feel hurt when my car's gas tank is left on empty after it has been borrowed." jill is using criteria. i-messages. metadiscussion. you-messages.

 I believe the answer is: I-messages

I messages refers to the effort that we make to assert the principloes, feeling, or belief that we have toward other people.
It's called I-messages because this process require the sentence to be started with 'I'.
For example, 
- I am very upset right now.
- I Think journalists should be held accountable for their articles.
- I think she is a nice girl.
