I think you’re starting to touch on the situation wherein the guy is a jackass.
I don’t know, sometimes I think it’s that panel of switches or maybe they’re just clueless. They may think if one switch does it for them.... (or maybe its the porn babes, I don’t know).
HOWEVER, I do know of one friends case where the guy really hated his mother (and sister etc) and while he acted like a great guy, perfect gentleman, even cleaned house, was generous etc, the way he got even was in the sack. Which was he flat didn’t care.
Passive aggressive is another reason I guess.
