Oh I don't know Guiltypleasures. My DH was very passive-aggressive (learned behaviour from his bloody horrible parents), but has now largely stopped ... erm ... being.
After DS was born we had a bit of a crisis (as so many do) and I nearly left him.
After some couples counselling and a lot of soul-searching and effort on both our parts, we sorted it out. We're still happy fve years on.
I think the key thing is that he needs to be willing to acknowledge it, and I think that it'll usually take a rocket up the arse for anyone entrenched in passive-aggressive power-play to 'fess up to their tactics.
Sorry OP - I know of no specific books. The way I dealt with it was to take EVERYTHING he said at face value and ignore any hint of sub-text. It takes an iron will, but it drives the passive-agressee bonkers, and eventually drives them into the open.
Example:
P-A: Are you wearing that today?
You: (Resist temptation to ask why he's asking) Yes.
P-A: Well, if you're sure.
You: (smiling brightly) Bye!
(Try kicking something hard after leaving the house and pretending it's your DH if you need an outlet).
HTH.
