Question

Restate the sentence, "You are not telling me what is going on!" to avoid assigning blame and make it a more neutral.

Answer 1

Sample Response: "I feel like we are not communicating as well as we could," or, "I hope we can both start communicating our thoughts better," are possible answers.

Answer 2

Is there something going on that you need to tell me?

This makes it so the asker of the question is blaming anyone yet, but is still trying to seek some answers from the other person.

I hope this helped you!
