This is first time I hear about medication helping with passive-aggressiveness. Depression, sure, but not passive aggressiveness. Look, you have tried to have him seek help for depression and failed - do not keep trying. I think my ex H is delusional and needs APs - his delusion, in my mind, is that I have ruined his life in every aspect of it including a bad renovation project done by a contractor whom he has selected without my participation. So I recommended a good doctor. Has he gone to see him? No. You husband is not going to listen to you either. Just forget about it and think about how YOU will spend YOUR life without him.
