Looking back...there's a lot of truth in this. 
I look at that statement in a kind of inverse way in that I was trying to heal something in myself by going with all those toss backs.
Not sure my plan worked out for any definable amount of healing, though, in retrospect.
Mainly, I hardened myself by doing all that. I did not start out this way, but before I met my wife, I had become a "user" of women because I had been abused so many times by, in my book at the time, really desirable women.
Once I began to "get over" my beautiful ex-wife, I was no longer afraid of "the best looking woman in the room" and went after it when I saw what appealed to me. I often set myself up for failure by locating someone in as bad a shape as I was in many cases. There were a few times of mutual healing happening though.
Many of my ex-s were somewhat "healing" to me in many ways, I thought. I'd say, Rare occurence.
No need to further my psychoses by explaing it all, but I feel like it was all just a way to grow and become better, so I would know when I was in a mental place where I could find The One. And know the difference.
Probably why it took me two years after meeting her to marry the best woman I have ever known.
Now, if we don't laugh at that shit then we may be more damaged than any "recall" can fix.
