Couples ideally rely on each other for emotional support and to fulfil their other emotional needs. You live with a person all day, every day. gradually begin sharing little details of your past, your present life and your aspirations about your future. And you begin to open your wounds to them. Then you start being vulnerable.
If he has gone from this kind of a relationship, to the point where he hardly talks about his feelings anymore, it might be that he is fulfilling his emotional needs somewhere else.
