I think to me my husband was like a family member. I would never get rid of or disengage from a child or brother or parent or even cousin no matter what, because they are family. No matter how selfish or unhappy I was. That's how I viewed my husband and marriage.
I guess he did not feel like that. Maybe because of his FOO issues (although parents stayed together) maybe because his friends are all divorcing? (I remember he proposed after his friends were all getting married)
I guess for me to detach I have to accept that husband does not think like me and is allowed to think differently and I have no control anyway.
Ok, I'm really just brainstorming at this point. I have no idea.
