Goku was you're beloved wife, you were married together for a year, you're relationship was pretty smooth until Goku fought Majin Buu to save the universe and was forced to permanently fuse her body with Vegeta to stop Majin Buu. So when she came home that night covered in bruises and still wearing the potara earrings, it was gonna be a long explanation.
"I'm so sorry baby, but I had to. It was for the sake of the universe."
You understood the stakes that were at hand and it was hard to be upset at the decision to permanently become one person, but it was undoubtedly going to complicate your marriage tremendously.
"I am neither the woman you married or Vegeta anymore, I am both, but also my own being."
She looked at you sincerely.
"I would understand if you filed for divorce. But I have the memories and feelings of Goku and Vegeta, and they both love you very much. Even though Vegeta never told you."
