David Grason on how/why he become MGTOW:

The problem with being a SIMP is that NPD women, such as my ex-wife, depend on men being so easily manipulated. This is how so many women actually develop this incredible sense of feminine entitlement. My ex never had to invent anything. She never had to build anything. She never had to cultivate or develop anything. She never had to solve any problems that were beyond her immediate attention. This was because she was so convinced of her female superiority that she approached men with absolutely zero doubt in her mind that they would fall down and become her bitches at the slightest hint of such a suggestion. The amazing thing was that SHE WAS CORRECT! If there was anything that she could not do for herself, she would simply go get the closest man to do it for her. I have always been in awe of her ability to assume any given man was a SIMP and assume correctly!

And to be honest, I was just such a SIMP in my younger years and she manipulated me. I honestly thought that I was doing the right thing. But when I saw the way my ex jerked other men around AND I saw how much gleeful, sadistic joy she took in it, I realized that I had been her bitch for a very long time and it needed to end if I were to ever have any respect. When I stopped being a SIMP, our marriage took a definite turn south. I stayed faithful to my marital vows but I put immediate skids on my SIMPness.
