Personal experience confirms what you say. Same kinds of people are attracted over and over, or same kind of problems repeat. Certainly not a coincidence. 
Again sometimes the most negative experience often lead to something positive or an outcome which wouldn't have happened otherwise which is of benefit. We easilly judge whats happening, and put our own emotion into it rather than learn and take what's most valuable. 
Alot of truth to all of this. Thanks. 👍
