My W sat me down for 20 minutes and lambasted me for the way I chew, comb my hair, wear my socks, park my car crooked in the garage, etc. ... the strangest thing was something I said on a date 14 years ago. Then something I wore to a party 8 years ago. The MLC mind is something medical science could study, and I'm sure funding would run out. It is bizarre and you've only seen the tip of the iceberg.
BD may haunt you for a while. You'll get to a point in which you don't get emotional over it. There may always be wonderment about if your actions/reactions may have changed things. But when you see this process play out you'll discover nothing can change the course.
