I agree with your assessment that your husband needs to deal with his negative attitude (connection with father, included) before moving again. I suggest that he's suffering from a combination of having been raised by and still influenced by a negative and abusive father which has resulted in his own depression. He sounds very depressed.
My mother was depressed but not abusive. Still, I grew up depressed and didn't realize it until I lost my first significant male relationship. I started in counseling and gradually saw how negative I was and learned to be more optimistic and proactive in making the life I wanted.
When we grow up with the depression it is difficult to recognize our own depression. I urge you to get him in for counseling and possibly medication. My psychiatrist told me that my chemistry was changed by my chronic depression and that talk therapy would help I needed the medication to straighten out the chemistry.
Good for you for being proactive. Arranging the move to California was difficult and now you're probably depressed because it isn't working. It's very difficult to live with a depressed person. I had to go back on medication when I married a man who turned out to be extremely depressed. So, counseling and/or medication may be of help to you also.
I understand why you'd want to move back to the islands. I encourage you to work in that direction.
I agree with Laurie D. A trip to the East would put living there in better perspective.
