When people have a joint account, it is often expected that both parties will consult each other before any large sum of money is moved in order to avoid one person feeling betrayed or let down
Context: I felt let down by my girlfriend when she decided to move some money out of our joint account without telling me.
Hypothesis: I felt let down when my girlfriend moved some money out of our joint account without telling me

Is the hypothesis incorrect? (Yes, no, or unknown)?
