I think when we hear these little tidbits of info, it causes us to take our focus off ourselves and put our focus back on them. I think it's a good idea to make it a habit of recognizing that, and doing our best to get our focus back on ourselves. Did the relationship make me happy? Could I be my best self in the relationship that I had? And when thoughts that focus on him or her pop into our minds, we have to tell them to go away!
