I have tried to take the perspective of my former partner, but I am finding this very difficult. Every time I step inside of his world, I see that he has lost great opportunities and has done this deliberately. Can you help me? Am I missing something when it comes to what you call “taking the other’s perspective”?
I would like to suggest an important addition to your exercises of taking your partner’s perspective. You seem to consider him primarily at the time of your conflict and his leaving. Yet, is there more to him than this? For example, was he abandoned as a child? Did someone emotionally wound him as a child or adolescent so that he now is so wounded that he cannot endure a healthy relationship? My point is this: I think there is more to him than his apparent insensitivity to you in the recent past. Is it possible that he has brought a certain brokenness into your relationship? If so, how are you viewing him when you realize this, if it is true?
