IMHO, your ability to see the male perspective - and I doubt all of that ability came from your ingestion of the M/V book, made you a very safe woman for SO to approach. And in comparison to most OW, he had no better option for a friend and more in you. Nicely done! - especially since this likely involves great work and flexibility and effort to understand on your part.
I've appreciated your take on men and on women. If you can do it, so can we!!
