I think he feels that if he didn't have me as his wife, he would no longer have to consider me when he makes a career decision. If I was just his friend, he could have a relationship with me that wouldn't involve that consideration.

This sounds familiar to me, as my husband brought this same topic up several years ago. It seems that sometimes a man who is responsible for others (wife, family) will often get these thoughts and not know what to do about them. He wants to be free to either keep or change a career path (part of Midlife stuff), but then he has to consider how this will affect the family...and it's just too much to handle. He may consider ditching his family, not because he hates them, but because he can't cope with all the complexities involved. Does this make any sense?
