What would happen if you changed your passwords? Or let me rephrase, what's the worst that could happen if you changed your passwords? When there's an argument, what's his temper like?

It's not the greatest thing to have a sense of not trusting him to be there so that you can make an appointment. And not believing that you can confide in him about your emotions. Those are very important needs that are unmet at the moment.

Was there a changing point between you or were things always like this?
