NO criticism taken, I always love reading your perspective!!People do things for a variety of reasons, some make no sense(TO US)....That's the key...
I know a few guys that have wives they don't particularly care for, never have sex with, but get what they want out on the street...It may not even be sexual...Heck, I have had more than one admin assistant/office manager work for me that treated me awesome and who I would consider very close......Like a lot of guys they spend a lot, of time at work, and would see and interact with these women more ways than their wives...If you are a typical guy that is spending 10-14 hrs a day with a woman who (may or may not sexually) meets "your emotional needs" then that takes a lot of the misery out of it, I guess...
Maybe the reasons you aren't getting all of it(and this isn't a criticism, btw), is that you are approaching this from the mind of a woman...I didn't create this idea, but it's often said that men have a mastery of compartmentalization...In these cases, if you are good at compartmentalizing these aspects of your life, then what may seem unbearable from those on the outside is just fine for the guy that has it figured all out...
