I haven't seen any activity on the board for a while...

I have a question about apologies. After having a calm and effective
discussion with my DH, he had to end it with a passive aggressive
comment. When I told him that what he had said was a passive
aggressive statement, he told me I was being a bitch. I told him that
was uncalled for and that I would not speak to him again until he
apologized. Surprisingly, he did give a genuine apology a few minutes
later.

When working with PA people, what is suggested to encourage them to
accept responsibility for their behavior? I've been trying different
methods and the best I've found is to "retaliate" in passive
aggressive form: i.e. saying I will not talk to him until the issue is
resolved. I understand that the difference here is that I tell him
the cause and effects of what I want to happen. What has worked (or
not) for everyone else?
