Knowing myself, I seriously doubt that I will ever care less about my xh.
You might be surprised! Perhaps feeling "different" is a better term. You want to see them "do well" but somehow or another, the person you fell in love with might no longer be there. For me, I was "in love" with what we had. Once that was for the most part trashed, I shifted my love to what exists now. Either way, time heals... Just be patient.
