Background: many years ago we almost split up because dh accepted a job without telling me (I didn't even know he had applied and found out because other people congratulated me on his new position). I was very upset as we had been planning on moving abroad and he hadn't told me he had changed his mind and just expected me to be happy for him. 
Fast forward 15 years and he casually dropped into the conversation that he has resigned from one position he does one day a week (and has done for 15 years). I am furious. Not because he wanted to give it up (fine - we will have slightly less money but he was finding it stressful) but because, again, he never thought to tell me let alone discuss it beforehand. All his colleagues know.
I just feel completely lost. After the first time when I wanted to leave I thought he had understood that for me marriage means talking to each other, discussing things. This has been an ongoing theme in our marriage and I am fed up. Am I unreasonable?
